Abstract
In this paper, we present the simulation results of the comparative investigation of the performance of the wireless sensor network routing protocols based on different routing objective: energy-aware routing using PROWLER and RMASE. Our simulation results indicate that the energy-aware routing objective increases the network lifetime for the Adaptive Tree, Constrained Flooding and Real-Time routing protocols than the default shortest path routing objective for Normal Radio Model, Radio Model with SINR, Radio Model with Rayleigh Fading and Radio Model with Rician Fading. It has been concluded that the network lifetime is longer with energy-aware as compared to shortest path routing objective. The energy-aware routing objective o = emax/(e+1) gives better lifetime than o = (k х u) + 1 for CF and AT routing protocols. It has been shown that without changing the routing strategy and by using the right routing metrics routing protocols can be made energy-aware to increase lifetime.
