DBMLE: Distance-Based Multi-Level Elliptic Routing Protocol for Ad Hoc Networks

Abstract

A critical challenge in the design of Ad Hoc networks is the development of an efficient routing protocol which provides high quality communication. The node's in MANET have limited communication resources such as bandwidth, buffer space, battery power etc. The resource constraints in MANET require the traffic to be properly distributed among the mobile host. The distance based multi-level elliptic routing protocol proposed in this paper is an efficient method of selecting the node as a next hop node, while communicating in a mobile Ad hoc network. The proposed method selects the node's which are orthogonal to the centroid. Here the node uses the position information to identify the nodes which lie in orthogonal direction. The node obtains location information from the GPS location service. The GPS location service fails to give accurate position information in constrained environments such as node not exposed to GPS satellites. In these scenarios, the node fails to get the location information. The error caused leads to locating the node to improper position. Therefore DBMLE protocol used in this paper uses communication signal strength along with the GPS information. The nodes keep track of neighbor node's position, velocity and signal strength information.
