are generated for the same destination. All these packets go through the
same route in a session when using current geographical routing. However,
detour is inevitable in geographical routing without the help of global
state. A progressive yet effective strategy is proposed to mitigate inefficient
detour in geographical routing. In asymptotically optimal geographical
routing, detour mode was substituted by greedy mode with the help of a
subset of nodes acting as way points. The average performance of the proposed
algorithm is compared to Greedy Perimeter Stateless Routing (GPSR) and
the benchmark shortest path algorithm. Simulation results show that in
average the proposed algorithm can reduce as much as 50% of hops on the
routes obtained by GPSR.]]>Akyildiz, I.F., T. Melodia and K.R. Chowdhury,200751921960Al-Karaki, J.N. and A.E. Kamal,200411628Blazevic, L., J.Y. Le Boudec and S. Giordano,2005497110Gurses, E. and O.B.
