Abstract: Reliable and energy-efficient transmission of sensory data is a key problem in wireless sensor networks (WSNs). This is due to resource constraint and it is necessary to present a new routing algorithm that can provide these requirements in network layer. The main objectives of multipath routing protocols are to provide reliable communication and ensure load balancing as well as to improve quality of service (QoS) of WSNs. Satisfying Quality of Service requirements (e.g. reliability and delay constraints) for the different QoS based applications of WSNs raises significant challenges. More precisely, the networking protocols need to cope up with energy constraints, while providing precise QoS guarantee For this purpose, we propose a new reliable and energy balancing multi path routing algorithm (REMP) for wireless sensor networks. The REMP protocol guarantees the mentioned quality of service parameters in wireless sensor networks and balances the energy consumption in all sensor nodes. By means of simulations, we evaluate and compare the performance of our routing protocol with the MCMP (Multi-Constraint Multi-Path) and EQSR (Energy Efficient and QoS aware multipath routing protocol) routing protocol. Simulation results have shown that our protocol achieves more energy savings and higher packet delivery ratio than the other two protocols.
