A wireless sensor network (WSN) consists of numerous distributed, self-sufficient micro sensor nodes to agreeably monitor physical or environmental circumstances, such as temperature, sound, vibration, pressure, moisture, traffic, motion, pollutants or habitat monitoring etc. Event based WSN rely on the combined effort of a number of micro sensor nodes. Reliable event detection at the sink is based on combined information provided by source nodes, not on any individual report. Hence, conventional end-to-end reliability description and solution are unsuitable in Wireless Sensor Network (WSN). Moreover simultaneous multiple event detection is an issue for a large sensor field consisting of thousands of sensor nodes which is discussed in Event-to-Sink Reliable Transport protocol with some issues needed to resolve. In order to address those need, a new simultaneous multiple event reliable transport scheme for wireless sensor network (WSN), is proposed in this paper. SMESRT is a transport solution designed to accomplish simultaneous multiple reliable event detection in wireless sensor network (WSN) with minimum energy expenses. It includes a combined payload control component that serves the dual purpose of less traffic at the sink and conserving energy.
