Abstract

A Wireless Sensor Network (WSN) is a set of self-powered sensor nodes. These nodes are deployed in infrastructure less mode to collect the useful information from the environment and transmit it to the sink node. The significance of Wireless Sensor Networks has been evidenced in many applications like military areas, health monitoring and observation of earthquake etc. However, WSN has also some limitations including limited energy supply that leads to shorter life time of the network. Although numerous techniques have been proposed to improve the life time of sensor nodes, yet the large energy requirements for communication activities is still a serious issue. In this work, Segregated Receive and Relay (SRR) based routing scheme has been proposed to increase the lifetime of WSN. To achieve the purpose, relay nodes have been introduced in interior regions of the network area. The results confirm that proposed scheme significantly reduce the energy consumed by interior region nodes, which proves the usefulness of the proposed scheme in prolonging WSN lifetime.

无线传感器网络中分离的通信接收与中继方案

无线传感器网络(WSN)是一组自供电的传感器节点。这些节点以较少基础设施的模式部署，从环境中收集有用的信息并将其传输到汇聚节点。无线传感器网络在军事、健康监测、地震观测等领域的应用已经得到了充分的证明。然而，无线传感器网络也有一些局限性，包括有限的能量供应，导致网络的寿命较短。虽然已经提出了许多技术来提高传感器节点的寿命，但通信活动对能量的巨大需求仍然是一个严重的问题。为了提高无线传感器网络的生存期，提出了基于隔离接收中继(SRR)的路由方案。为了达到这一目的，在网络区域的内部区域引入了中继节点。结果表明，该方案显著降低了内区域节点的能量消耗，证明了该方案在延长WSN寿命方面的有效性。
