022597SivakumarThe convergence of micro electro-mechanical systems (MEMS) technology, wireless communications and digital electronics have enabled the development of low cost, low power, multi-functional sensor nodes that are small in size and communicate un-tethered in short distances. They can perform tasks, which traditional stand along sensors are hard to match. Although sensor networks have some similarities with another class of wireless networks called ad-hoc networks, they have several distinguishing characteristics that necessitate dedicated communication protocols.The PIs overall objective in the proposed project is to develop a system architecture, which includes new protocol entities and interfaces. Their focus will be on the integration of the proposed algorithms into an efficient overall system. While they propose to develop new algorithms and protocols for the transport and network layers, specifically, their deliverables will include: (a) a new transport protocol called SNTP (Sensor-Nets Transport Protocol) that is designed specifically for a sensor network environment, and (b) a power aware and scalable routing protocol that allow an end-user to control the sensors and reconfigure the interconnection of the sensor network. The PIs will evaluate their proposed protocols in a ns2 network simulator based simulation environment, and make available for public use any protocol simulation software. Since the ns2 simulator currently does not extensively support the simulation of sensor network environments, they will also develop such support and make it available for public use.

微机电系统（MEMS）技术、无线通信和数字电子学的融合使得能够开发低成本、低功率、多功能的传感器节点，这些传感器节点尺寸小并且在短距离内不受约束地通信。它们可以执行传统的沿着传感器难以比拟的任务。虽然传感器网络与另一类称为ad-hoc网络的无线网络有一些相似之处，但它们有几个显著的特点，需要专用的通信protocols.The PI的总体目标是在拟议的项目中开发一个系统架构，其中包括新的协议实体和接口。他们的重点将是将所提出的算法集成到一个有效的整体系统中。虽然他们建议为传输和网络层开发新的算法和协议，但具体而言，他们的交付成果将包括：（a）专门为传感器网络环境设计的称为SNTP（传感器网络传输协议）的新传输协议，以及（B）允许最终用户控制传感器并重新配置传感器网络互连的功率感知和可扩展路由协议。PI将在基于ns 2网络模拟器的模拟环境中评估其拟议协议，并提供任何协议模拟软件供公众使用。由于ns 2模拟器目前并不广泛支持传感器网络环境的模拟，他们也将开发这种支持，并使其可供公众使用。
