A modify the directional aware nodes using LAR Routing Protocol & GPS technology in MANET

A lot of routing protocol used for MANET. In this paper we are using LAR protocol to find location of node. The Location-Aided Routing (LAR) protocol is an on-demand scheme. It utilizes location information to perimeter the route uncertainty flooding area. The precondition is that all hosts know it´s possess position and the universal time, which can be provided by a Global Positioning System (GPS). Two scheme are used in LAR protocol i.e. Request zone and Expected zone. In this paper we are proposed algorithm for expected zone. Expected zone is divided into six segments and easily finds away destination location. The proposed approach is suitable for both high and low stupidity network. The aims of this paper are straightforwardly find the position of node and also find the direction of node using probability distribution function (PDF). Location Aided routing protocol reduce in the clouds the network so that it needs less calculation to find the location of destination. Location Aided Routing Protocol (using PDF) and Dynamic Source Routing protocols (DSR) certain simulation scenario is run. Results show that proposed algorithm increases the throughput in MANET and WLAN. Besides calculating the throughput, proposed approach also enhance data dropped rate, load, and retransmission attempts in ad hoc network.
