PERFORMANCE TUNING FOR GEOGRAPHIC ROUTING IN WIRELESS NETWORKS
Journal Title: International Journal of Engineering, Science and Mathematics - Year 2012, Vol 2, Issue 5
Abstract
To accomplish fast and location error independent and energy-efficient message delivery in ad hoc and wireless sensor networks, we propose PEOGR, a simple geographic routing protocol. POEGR is reliable routing protocol in that nodes do not need to set up or maintain routing or neighbour tables; instead, POEGR routing via its „„Angled Probabilistic Relaying” mechanism and uses the „„Backup and relay cancellation” mechanism to reduce contention and the number of retransmissions. One of the main features of PEOGR is a message based ACK mechanism where a relayed message is used as an ACK to a previous sender. In this paper we provide an algorithm and extensive analysis of POEGR in terms of average hop count and average delay per hop. Simulation results also show that POEGR outperforms other protocols in terms of average delay and number of transmissions per message delivery.
