Cluster based Multipath Routing for Wireless Multimedia Sensor Networks
Ranjith Kumar A, Sivagami Amirthalingam · International journal of intelligent engineering and systems · 2016
Wireless Multimedia Sensor Network is extensively used in the transmission of the multimedia data such as video traffic, etc.This multimedia traffic is transmitted through large distances and hence cluster based multipath routing is widely used.The cluster based routing effectively routes the traffic through the network towards the destination.But, due to the heavy load on the cluster head because of the extensive cluster operation, the energy consumed by the cluster head increases, eventually leading to the death of the cluster head which affects the entire cluster and thus degrades the network operation.So, in this paper, we propose an efficient cluster based multipath routing technique in which each cluster consists of two cluster heads, one to collect cluster data and the other to transmit data.In this way, the overall load on the cluster head is shared between the two cluster head and this increases the cluster lifetime and efficiency.Then the data to be sent is prioritized and then transmitted through the corresponding priority disjoint paths to ensure successful delivery of the data as per the real time requirement.
