Dead state recovery based power optimization routing protocol for MANETs (DSPO)

Abstract

Mobile ad hoc networks are a set of small, low cost, low power sensing devices with wireless communication capabilities. The energy concerned is the receivers processing energy, transmitter's energy requirement for transmission, loses in the form of heat from the transmitter devices. All nodes in the network are mobile and for measuring the efficiency at particular instant, the nodes are considered to be communicating in half duplex mode. In this paper, we introduce the DSPU algorithm which is an automated recovery based power awareness algorithm that deals with the self recovery of the nodes in case of recognition of dead state thus preventing network model going into state of congestion and overheads. The DSPU is an enhanced form of AODV protocol that has the ability of self recovering regarding the security issues of the network structure. The simulations are performed using the NS2 simulator [11] and the results obtained shows that the consideration of energy, bandwidth and the mobility factors enhances the performance of the network model and thus increases the throughput of the ad hoc networks by increasing the life of the nodal structure. © 2011 Springer-Verlag.
