摘要：Recent advances in micro electro mechanical systems (MEMS), wireless communication, and network technology, wireless sensor networks (WSNs) have become technically and economically feasible. In most case, WSNs are usually applied to many applications that require unattended operation. However unlike traditional networks, WSNs are resource constrained distributed networks. The delay latency, uncertainty and dynamic reliability of the WSNs may strongly impact on the WSNs applications. The information content or meaning of sending and receiving data will happened frequency when exchanging data among these sensor nodes over the WSNs. In addition, the application protocol themselves for data exchange may also impact on the WSNs applications. An inappropriate protocol will result in serious inefficiency so as not to meet application requirement. In order to ensure the reliability, integrity, and the continuity of data operations on the WSNs, this paper presents a delay-aware application protocol for WSNs applications. This protocol is based on ZigBee protocol that is suited for remotely monitor and control because of its low-power. Simulation results show that the protocol is feasible for the wireless sensor network in terms of the reliability, integrity and continuity of data.
