In the other side, local aquaculture sector also contributes to the market. A significant quantity of both aquaculture and fisheries production is exported outside Gaza to West bank. The fish auction which is held every day is monitored by the ministry of agriculture, and a broker manages the auction. The fishery sector, including catching and farm fish, from fishing to vending in the market, suffer a lot of difficulties and problems related to the supervision and monitoring because there is not a platform to automate all processes. These processes need to be controlled and monitored by a management system. Our proposed fish market management system (FMMS) connects all stakeholders of the fish market: fishermen, ministry of aquaculture, aquaculture farms, traders, restaurants, and exporters. Moreover, the ministry of Health can record their monitoring related healthy and quality information on the system. The customer in the other side can use the WikiFish mobile application to enquire about any information related to any fish species: its source, quantities in the market, prices, types, etc. by scanning fish image; the application is supported by image processing and Artificial Neural Network (ANN) algorithms to train the system. The system will manage the data of the fisheries sector effectively, and its impact will be obvious by improving the customer’s overall experience by better managing interactions, from sales to customer service and marketing, therefore, determine productivity, fidelity, and overall success.
Consumers of the fish market around the world face problems in the identification of fish species... more Consumers of the fish market around the world face problems in the identification of fish species and people need to obtain expert assistance to do so. This situation is typically the same in Gaza Strip, the local fish market lacks such an application that exposes people to fraud by some sellers. On the other hand, many poisonous and exposed fishes were caught and sold in the fish market in Gaza Strip. Thus, in this work, an innovative mobile application is proposed for identifying fish species that are commonly available in the Mediterranean Sea and therefore in the local fish market. A considerable number of fish images as a dataset were obtained from El-Hesba and auction markets located next to Gaza Fishing Harbor of Gaza as well as aquaculture farms. The AlexNet was chosen for the proposed model. Moreover, RELU SOFTMAX was chosen for the main network the model exhibit accuracy of 80 %, 0.788 precision and recall of 0.631.

There has been widespread progress regarding the application of Blockchain in the financial field. Using the blockchain technology in the financial field, resulted in the creation and establishment of multiple applications of Blockchain Wallets based on Blockchain technology. For Gaza Strip residents who suffer from the siege and closure of crossings because of the occupation, there are many difficulties in performing financial transactions and banking deals. As a contribution, to facilitate financial deals in Gaza strip we created the Gaza Wallet under the Blockchain technology. Gaza wallet deals with its currency called Gaza Coin (GC). It facilitates the conduct of trade and financial operations with less cost and without any intermediate third-party. Gaza Wallet has two applications, one is a web-based and the other is a mobile application using the QR Code technology. Individuals can access Gaza wallet through mobile or web application for payments, to store cryptocurrencies, or to manage their balances.

These problems lead to inefficiencies in the Application level. For localization algorithms in wireless networks, efficient handover protocols and multimedia delivery information, these problems must be solved. A figure used to control the connectivity of terminals to other terminals or to an Access Point (AP) is the well known Received Signal Strength Indicator (RSSI). Managing this figure it is possible to control the availability of a service in the wireless terminal. But the problem with RSSI is the fact that it exhibits high variability in space and time. Thus it is important to filter those values in order to efficiently manage the availability of the service in the mobile terminal. For that reason in this paper we present the experimental validation of a filter and a predictor of availability of a service in the wireless terminal based o...

They can interoperate to form a wide geographical network in which Mobile Client (MC) can move. We suppose a combination of two WiFi Access Points (AP) and a WiMAX Base Station (BS) that interoperate putting a WiMAX Wireless Network Interface Card (WNIC) in the WiFi AP. The BS can request real time video or Video on Demand (VoD) from a server allocated in the fixed network (to which the BS is connected). In order to model the movement of the MC, we build a diagram state to represent the areas in which MC can stay, and from what area to which one the MC could pass. Classifying the areas in connected and disconnected ones, we can discover the different actions that are achieved by different entities of a simple protocol, that are allocated in the BS and the AP.

Los Clientes Moviles (MCs) podrian experimentar interrupciones en las zonas de desconexion: handover, fuera de cobertura o los agujeros donde se pierda la senal de manera subita e inesperada. Por lo tanto, nuestro objetivo fue desarrollar un protocolo para mitigar los problemas de interrupcion del servicio de video durante las desconexiones de corta duracion en redes WiFi. Hemos propuesto un protocolo basado en novedad especificacion matematica para el Area de Cobertura (CA), que consta de dos tecnicas importantes: el Predictor y el Filtro del Indicador de la potencia de la Senal Recibida (RSSI) Gradiente, y la tecnica de la gestion del buffer y del control de velocidad de transmision. El protocolo se ha especificado y verificado con el Lenguaje de Especificacion y Descripcion (SDL), y se simulo usando un simulador especifico de Java derivado del diagrama de SDL. La prueba experimental del Filtro y el Predictor Gradiente ha demostrado su eficacia en la prediccion del proximo nivel de cobertura del MC, y su capacidad de mitigar el efecto de los agujeros. Tambien se mostro el mejor rendimiento en comparacion con el filtro de Kalman y el modelo de Grey. Los resultados de la simulacion demostraron que el protocolo es adecuado para todos tipos de desconexiones causadas por los agujeros, el handover, o fuera de cobertura que constituye un nuevo avance en comparacion con anteriores tecnicas disponibles. Ademas, ofrece la suficiente cantidad de video frames en MC Buffer (MCB) para consumirlos durante las desconexiones mencionado (aunque por mucho tiempo), resultando en video jugando adecuado continuo y ofrece suficiente tiempo para el usuario para pasar de una CA a otro sin interrupciones

Worldwide Interoperability for Microwave Access (WiMAX) and Wireless Fidelity (WiFi). They can interoperate to form a wide geographical network in which Mobile Client (MC) can move. We suppose a combination of two WiFi Access Points (AP) and a WiMAX Base Station (BS) that interoperate putting a WiMAX Wireless Network Interface Card (WNIC) in the WiFi AP.

These entities are in charge of controlling the buffers to efficiently support disconnections due to handover and out of coverage situations (disconnected states). Our algorithm is based on Received Signal Strength Indicator (RSSI)
measurements. These RSSI values are used to change the state in the diagram state. But to predict the next state of MC, we use a new prediction technique that we call RSSI Gradient Predictor. We test our predictor using some synthetic proposed RSSI values for different MC movement shapes. These movements include Regular and Irregular movements. The results show a good behaviour of our algorithm.

microphone system that depends mainly on FM radio frequencies. These systems have unexpected problems such as no enough microphones, interferences, weak signal, running out of battery life, unwanted noise, and feedback. Moreover, extra equipment is required if the speech needs recording. The proposed solution is “MyMic”. It is a mobile application developed by ALTARIQ Systems & Projects to solve the previous issues. The main idea of the application is using the smartphone connected to WiFi as a wireless mic. A control panel running on PC/Tablet (server) manages Mobiles (Clients); it receives the
sound streams using UDP packets and sends processed sound stream to the sound system. The control panel allows multiple speakers simultaneously. System testing inside a hotel event hall was successful with clear sound of three simultaneous speaking users where noise values were 4.7 % in average.

Short term client sporadic and not previsible disconnections lead to service interruptions which provoke a user headache especially if a firm real time multimedia service is used and a hard error when a real-time service (e.g. vigilance) is used. Also, during handover process channel conditions deteriorate leading to data loss. With multimedia services, handover influences packet loss, this is avoided by handover prediction mainly. Many handover prediction strategies use Received Signal Strength Indicator (RSSI) as the basic indicator for disconnection. Filters like Kalman and Grey Model (GM) are used by many researchers to estimate the RSSI value. These filters adapt rapidly the prediction to the continuous RSSI. This means that they can not work with short disconnections. In this paper we present a new RSSI Gradient predictor and filter technique capable of controlling short disconnections efficiently. The RSSI Gradient filter has been theoretically tested supporting well a long set of random Mobile Client (MC) movements inside the coverage area where coverage holes can be considered novelty.
