Wireless sensor networks consist of hundreds and thousands of nodes which are deployed to sense parameters related to the surroundings such as temperature, moisture level, pressure etc. Network topology and energy consumption are important issue in WSN for improving network performance in critical applications. The cluster-based routing is the best way to decrease energy consumption by reducing the number of hops to transmit messages to the sink node. The cluster heads are responsible for gathering data from cluster members and forwarding them to the base station. Hence the cluster heads are expected to be more energy efficient compared to other sensor nodes. LEACH is the popular cluster-based routing protocol in which cluster heads are selected on a rotation basis. It is based on the assumption that sensor nodes can directly communicate with the sink node. We propose a CCE Virtual Backbone cluster-based routing protocol to overcome this assumption by selecting cluster heads using generated Virtual back bone path with multi-hop routing protocol. Virtual back bone path calculation is based on the parameters like message success rate, communication cost, and maximum connectivity. It is proved that our protocol highly reliable energy efficient and increase the life time of the network.
