An energy efficiency and delay guarantee service selection protocol in MANET

The real-time applications deployed in MANETs are affected by the mobile node´s power constraints and the real-time database service provider´s system stability. In this paper, we aim to handle the time-constrained requests within their deadline despite of the mobile nodes limited energy. We propose a cross layer service selection protocol which ensures both timelines and energy efficiency. The proposed solution discards low-power route, overhead route and overloaded service provider. We evaluate the performance of our proposed protocol using the NS2. Simulation results show that the protocol decreases the deadline packet´s miss ratio and reduces the energy consumption.
