Energy Aware Multipath Routing Protocol for Wireless Sensor Networks

Conference paper
Part of the Lecture Notes in Electrical Engineering book series (LNEE, volume 131)

Abstract

Wireless Sensor Networks (WSNs) are made of sensor nodes with restricted battery life and transmission capability. In this paper we propose an energy efficient multipath routing algorithm in WSN. This protocol is designed to improve the lifetime, latency and reliability through discovering multiple paths from the source to the destination. It has a sink initiated Route Discovery process with the location information of the source known to the sink. There are two types of nodes which are used here one is primary and the other is alternate. At the end of the route formation one primary path and a number of alternate paths are built and all nodes except the primary are put to sleep mode which helps us to save energy and generate a collision free path, the primary path is used to transmit the data from source to the sink and if the route disrupts, the next best alternate route is used for the purpose and if no path exists between the source and destination then process starts from the beginning. Further, we analyze how the proposed protocol overcomes the drawback of the existing protocols.
