Reliable event delivery at MAC, routing and transport level has been explored to great extent to provide improved throughput and route resilience in wireless sensor networks. The evolution of wireless sensor and actor networks (WSAN) have posed an extra constraint in terms of reliable event response. The reliable response is defined as the the in time event delivery from sensor nodes to actors and timely action of actors against the sensors input. This might be required in an application that includes a diverse mixture of sensors for monitoring multiple events. In this paper, we propose a reliable event response (RER) framework for WSANs that addresses the issue of reliable action. RER implements two functions, reliable event delivery (RED) and prioritized event action scheduling. RED is based on a a novel cluster-based multipath routing protocol. While, action reliability is ensured through a prioritized action scheduling based on earliest deadline shortest positioning (EDSP) algorithm. The results reveal that RER achieved its goal of action reliability which is not possible with simple scheduling first-in first-out (FIFO) scheduling algorithm.
