چکیده مقاله:
Energy-efficient and reliable data transmission are crucial issues in WSNs due to the energy constraints and high packet loss rates, In order to increase network reliabilityand throughput, multipath forwarding is used in many applications. However because of using multiple paths between source and destination, the multipath forwardingmechanism increases network overhead. By splitting the original messages and forwarding each sub-packet through multipath routing protocols, energy consumption andnetwork overhead can be reduced. This paper proposes a flexible recovery mechanism which increases reliability and minimizes both energy consumption and delay. Theproposed scheme caches sub-packets at some special intermediate nodes and retransmits from these nodes instead of source node whenever it is necessary. Performanceevaluations of sub-packet caching (SPC) demonstrate that using multipath forwarding with caching data can effectively increase reliability and reduce energy consumption andlatency.
