Multipath data transfer in wireless multimedia sensor network

The Wireless Multimedia Sensor Networks (WMSNs) consist of nodes that are capable of sensing, computing, communication, actuation, and power components. Some of the applications of the Wireless Sensor Multimedia Networks include habitat monitoring, target tracking, environmental monitoring, and traffic management systems; these applications require effective communication of event features in the form of multimedia such as audio, image, and video. Routing in Wireless Multimedia Sensor Network is an important issue since the WMSN nodes that sense the data need to be communicated to the base station, to take necessary decision. The key issues in the design of routing protocol in the WMSN are energy consideration, multimedia consistency, tight QoS expectations, and high bandwidth demands. Although many routing protocols have been proposed for the WMSNs, the design of a more efficient protocol in terms energy awareness and QoS still remain a challenge. This work involves the design of the routing protocol in wireless multimedia sensor networks which is power aware, reliable and has low latency in delivering the data from source node that is sensing the data to the destination node/sink node. The proposed new algorithm called MPDT: Multipath Data Transfer protocol provides simultaneous multiple paths for communication between any two nodes. This feature prolongs the lifetime of the network. Also from the data security point of view, MPDT is immune to some specific attacks. Simulation results show that the proposed protocol surpasses the conventional protocol in terms of energy consumption and network lifetime.
