Abstract

Wireless sensor network (WSN) consists of numerous sensor nodes which are deployed to inspect a certain subject. As a stream of packets from the source node is sent to the sink, the data has to reach without any delay or loss of packets. The key issue in WSN is that these networks suffer from the packet overhead, which is the root cause of more energy consumption in sensor networks. The previous works achieved are look-ahead bandwidth schedulers are deployed to meet high speed and to increase energy efficiency of WSN. Centralized and decentralized heuristic are developed and an energy harvesting method is used to maximize the network lifetime. To reduce redundant overhead and to conserve nodes’ energy a cross layer energy balanced bidirectional minimum hop routing algorithm is used. The sensors nodes in WSN are battery operated and are hard to replaced and recharge the battery of these nodes. Sometimes the mode of the node changes from active to sleep the efficiency decreases as data has to wait at the initial point. In this paper we provide a survey on how to maintain the energy efficiency incase if there are any dead nodes and to find an optimal path in which data can be transmitted. To achieve this we proposed energy aware routing protocol named as PDORP.
