Energy Conservative Opportunistic Routing(ECOR) in Wireless Sensor Networks
Main Article Content
Abstract
Wireless Sensor Networks (WSNs) are large collection of sensing nodes with processing and communication capabilities. The major issue in sensor network is limited battery power. Batteries cannot be recharged or replaced once deployed. Research on wireless sensor network has recently received much attention as they offer an advantage of monitoring various kinds of environment by sensing physical phenomenon. Recently Opportunistic Routing has emerged as a novel routing scheme that effectively improves the capacity of a multi hop wireless sensor networks. It takes the advantage of broadcast nature of wireless communication. In contrast to traditional unicast routing, where the next hop forwarder is formed before the transmission of data. Opportunistic Routing chooses its forwarder list dynamically with poor energy management. The performance of Opportunistic Routing is enhanced with energy conservation algorithms and higher throughput and thus network lifetime is increased.
