Extended Position Adaptive Scheme for Effective Beacon Transmission

Kalaiyarasi.R, Rajeswari.S

Beacon and data transmission is based on the location information of each and every node which is connected in the geographic routing network. The beacon packets are transmitted to requested node by the neighbor node, using APU (Adaptive Position Update) scheme.APU scheme incorporates two rules are On- Demand Learning (ODL) and Mobility Prediction (MP) rule.APU dynamically adjust the beacon update interval based on the movement of the node. ODL rule is used to reduce the updating cost and also to improve the performance of the network.ODL creates the topology for the active nodes. But MP rule is not able to handle the link failure while transferring the data. Extended Adaptive Position Update (EAPU) scheme has been proposed to overcome that drawback. It has two ways to overcome the link failure, inaccuracy of the topology and performance degradation. The two ways are 1) Request for new neighbor node’s neighbor list.2) Verification of acknowledgement, Transmission and path.
