Abstract

Wireless sensor networks, an interconnection of energy restrained devices used for sensing environmental variables and then transmitting these to sink by manipulating routes over communication medium between sensors and sink node. Major constraints in routing of sensed data are latency of network from source to destination and the other one is limited residual energy of nodes required for effective communication. Both of these are prime factors in designing of routing algorithms. In this paper we have selected geo-locations of nodes as principal variable for energy-efficient routing between nodes. Sensor nodes are equipped with differentiable technical specification over other nodes. Some of nodes have higher initial energies compared to other nodes and higher number of frequency channels than other nodes. Simulation and scenario has been generated in network simulator 2. Transmission power is calculated based on geo-location of nodes and tuned using software radio presets. Likeliness of forwarding packet is based on rationalizing residual energy of transmitting node and distance between nodes.

基于地理定位的异构传感器网络节能路由

无线传感器网络，一种能量限制设备的互连，用于感知环境变量，然后通过在传感器和汇聚节点之间的通信介质上操纵路由将这些变量传输到汇聚节点。传感数据路由的主要制约因素是网络从源到目的的延迟，另一个制约因素是有效通信所需节点的剩余能量有限。这两者都是路由算法设计的主要因素。本文选择节点的地理位置作为节点间节能路由的主变量。传感器节点具有相对于其他节点可微分的技术参数。有些节点的初始能量高于其他节点，有些节点的频率通道数高于其他节点。在网络模拟器2中生成了仿真和场景。传输功率是根据节点的地理位置计算的，并使用软件无线电预设进行调谐。报文转发的可能性基于对发送节点剩余能量和节点间距离的合理化。
