SDLAR: Self Adaptive Density-Based Location-Aware Routing in Mobile Adhoc Network

摘要

Nowadays, location aware routing protocols are accepted potentially, scalable and efficient solution for routing in MANET. The advantages of these routing protocols are that they perform route discovery in a smaller region known as request zone, instead of doing route discovery in the entire network. This shows that the size and shape of the request zone play a major role to enhance the performance of routing procedure. Hence, the paper proposes an efficient scheme which focuses on creation and adjustment of size of request zone to find a stable path with less communication overhead. The protocol confines route discovery within an ellipse shaped request zone to reduce the routing overhead and achieve path stability. Further, the proposed protocol uses a density metric to resize the request zone for successful route discovery. Simulation results show that the proposed protocol can help to improve the path stability with lesser routing overhead than LAR-1.
