ESMRsc: Energy Aware and Stable Multipath Routing Protocol for Ad Hoc Networks in Smart City

International audienceMobile ad hoc wireless networks are characterized by the absence of central administration and any network element may be very mobile. It may exist no fixed element within an ad hoc network. In fact, within these networks, all elements must cooperate so as to create a temporary network topology which enables communication. To create this topology and carry data, ad hoc networks must use efficient routing protocols. In this paper, we propose a multipath routing protocol with low energy consumption in order to improve the performance of mobile ad hoc wireless networks. Our protocol ESMRsc (Energy aware and Stable Multipath Routing Protocol in smart city) uses a path selection strategy which is based on energy constraint and link stability. Our protocol will be designed on a realistic mobility model, contrary to most existing protocols which are based on random mobility models with some unrealistic behaviors such as sudden stop, abrupt acceleration. Simulation results demonstrate that our protocol has better performance in terms of energy consumption and network reliability
