The paper presents a robust QoS centric routing protocol for mission-critical communication over mobile Wireless Sensor Networks (CL-mWSN) that exploits dynamic network states from the different layers of the IEEE 802.15.4 protocol stack to make the routing decision. The CL-mWSN protocol exploits three key layers: application layer, network layer and MAC layer. It exhibits proactive network and node table management, service differentiation, fair resource scheduling and congestion detection, avoidance at the network layer, as well as dynamic link quality estimation and packet injection rate estimation at the MAC layer to assess its candidature as the best forwarding node for QoS-centric mission-critical communication. Simulation reveals that the proposed routing model exhibits higher throughput, minimum loss and deadline miss ratio that augments QoS provision in mobile WSNs.

A brief exhaustive summary review of the various advances in the development of energy efficient distributed cooperative routing protocol for wireless sensor n/w’s in the current scenario is presented in a nut shell in this research article. This paper just gives a in-depth scenario into the various works of the authors & lays a foundation for the proposition of the works that could be done by the future researchers in the area of wireless sensor networks.
