Recent in- terest has been focused on low-power feature of the sensor nodes because the power consump- tion is always an issue for wireless sensor nodes which is supplied from the batteries. The eZ430RF2500 Development Tool from Texas Instruments have integrated MSP430 family of ultralow-power microcontrollers and CC2500 low-power wireless RF transceivers which are suitable for low-power, low-cost wireless applications. In this thesis, the features of these TI devices are explored and a wireless sensor network is implemented with these devices. To implement the routing algorithms we have assumed a hierarchical architecture, where one source serves as the access point for a number of sensor nodes. Before switching to a communication channel we scan the frequencies so that error can be minimised (Clear Channel Assessment) and thus increasing the reliability. Energy efficiency of the wireless sensor netw...

Use of a mobile phone for robotic control can overcome these limitations. It provides the advantage of robust control, working range as large as the coverage area of the service provider, no interference with other controllers. Also, the network area of the service provider is utilized; hence, it reduces the cost of additional wireless control equipment which can be expensive when applied on an extensive scale.

We can program these nodes to work according to our requirement and response according to the situation. These nodes are made capable of sensing, processing and communicating. With the rapid advancements in the technologies of software, hardware and communication methods a complete new range of communication network called Mobile Ad-Hoc Network (MANET) is being developed over a last couple of decades. Mobile Ad-Hoc Network holds a tremendous inbound potential, of which a lot has been discovered in the fields of effective bandwidth utilization, link weight awareness (LUNAR, OLSR), multicasting (PUMA), power source awareness, hybrid protocols (HAPR), biology inspired technologies (BISON), table driven and on-demand protocols (AODV), network life time optimization etc. and to these factors the network is made adaptive to the dynamic conditions; yet it is found that a lot of exploration could be done in some areas such as the efficient geometric arrangements of the nodes, method of power efficient routing, localization of the nodes, broadcasting and multicasting techniques, network formation and adaptation abilities and methods. In this paper, a systematic geometric approach to increase the range of a node is discussed. The concept is to temporarily arrange the nodes in specific formations so that the range of any node in the network can be extended virtually, making the data routing efficient in terms of energy consumption, delay, reduce error occurrences and time complexity. Some of the related theoretical results and NS2 simulation results of the geometric approach are discussed.

Wireless Sensor Networks are being used in various fields such as industrial, medical, military, disaster relief, etc. They have many proposed applications, and with every application come new protocols. Hence, a survey of the existing hardware platforms and communication protocols is necessary for a comparative overview as a first step in the deployment of wireless sensor networks for application to any field. In this paper we discuss the hardware platforms like Shimmer, TelosB, Ember, and two development kits of Texas Instruments. Also, widely used wireless communication protocols which use channel switching mechanisms have been discussed for improvement of reliable communication.
