GC introduces unexpected load and causes undesirable delays for real-time applications. In this paper, we propose a technique that reduces and bounds the memory requirements for real-time Java programs. This technique can eliminate or reduce the need for GC and allows for a more predictable execution behavior and efficient utilization of the available memory. A theoretical model is presented and a number of benchmark tests are used to evaluate this technique in PERC, NewMonics' realtime JVM, and Sun's JVM. The results show that in some cases GC can be eliminated and an application's execution time decreases and becomes more predictable.

The mechanism involves the collaboration of the software agents to collect, organize and efficiently exchange resources information. The main goal is to provide an accurate single system image for all the resources. The concept of virtual clusters is used to enhance localization of information and minimize exchanged messages. This mechanism is introduced as a part of the run-time support layer in Delmon. Delmon is a three-layer middleware framework for distributed systems, which includes the run-time support layer. This layer utilizes agents that reside on the participating machines and communicate with one another to perform the required functions. The agents hide the details of scheduling, controlling, monitoring, and executing user jobs, while the management of system resources is made transparent to the user. The proposed mechanism for collaborative resource discovery is based on the hierarchical structure of the agents and the organization and update protocols.

Recently Service-Oriented Middleware (SOM) has become a preferred platform for developing WSN applications over the more traditional development platforms to help address these challenges. SOM logically views WSN as a service provider for user applications. The SOM provides abstractions for the complex underlying WSN infrastructure through a set of services needed by the WSN applications. These services can be data aggregation, adaptation, security, self-organization, reliability, and management services. This paper surveys the current SOM solutions for WSN. The paper discusses the trends and challenges of designing and developing these solutions for WSN.

This introduces unexpected load on the system and causes undesirable delay for the real-time applications. In this paper, we study the realtime Java (RTJ) specification and some of the available implementations of RTJ such as PERC and Jbed. The main objective of the study is to determine the memory management tools provided for real-time applications that require frequent object creation. Based on this study, we propose an object-reuse technique to reduce memory requirements of intensive object creation in Java programs. This technique eliminates the need for using garbage collection and allows for a more deterministic task execution and efficient utilization of the available memory. A theoretical model is discussed and a number of benchmark tests are used to measure the different aspects of this technique. The benchmark results show that garbage collection can be eliminated and the execution time of the applications has improved. The results obtained motivated introducing a framework for enhancing and automating the object reuse technique.

One major obstacle is resource discovery in the presence of mobile nodes. Collaborative resource discovery mechanisms are available to handle static to semi-static resources. However, incorporating mobile users introduces a different set of problems. First, how do we know when a resource becomes available? How do we identify the resource, its current location and its moving patterns? A middleware framework to conceptualize the mobile environment and the associated issues is introduced. It involves the collaboration of software agents residing on the group members' nodes to collect, organize and efficiently exchange resources information.

Object passing provides the object-oriented application developer with powerful yet simple methods to distribute and exchange data and logic (objects) among processes. The model extends message passing, while exploiting the advantages of the object-oriented paradigm. In addition, the model provides a portable framework for executing applications across multiple platforms, thus effectively exploiting available resources to gain more processing power. A number of advantageous aspects of adopting object passing are discussed, in addition to highlighting the differences between message passing, represented by MPI, and object passing. Another advantage is the model's suitability for heterogeneous systems. When implemented with a portable language like Java, it can support parallel and distributed applications spanning a collection of heterogeneous platforms. This form of execution will eventually allow for full utilization of available resources for any given application written using this model.

Routing protocol in wireless sensor and ad hoc networks discover a multi-hop route between source and destination nodes. This paper presents RAS: a Reliable routing protocol for wireless Ad hoc and Sensor networks. In the RAS protocol, increased reliability isachieved by the maintenance of a reliability factor by the nodes. The value of this factor is increased when nodes participate successfully in data transmissions. This is determined through the use of positive and passive acknowledgements. During the path discovery process, an intermediate node only extends the request message to nodes that have a minimal reliability factor which is specified by the source. Additional optimizations are included in order to increase the efficiency and performance of the network. Full Text at Spring...
