Abstract

We propose an adaptive clustering protocol in heterogenous wireless ad hoc networks (HANETs). Our protocol is an energetic sustainable protocol that adaptively forms clusters and makes a hierarchy of cluster heads and cluster members. This technique reduces the heavy duty of data transmission to the base station. Cluster heads collect data from the members and transmit that to the base station on behalf of all the nodes in the cluster. The challenge is to rotate the cluster heads appropriately among the nodes at each round such that the assigned workload matches the residual energy of each node. In our protocol, we keep track of the nodes’ residual energies and select the stronger nodes more frequently as cluster heads. This challenge is particularly critical in recently developed HANETs where the nodes could be wireless IoT devices, cellphones or cars with different tasks and energy levels. The state-of-the-art adaptive clustering protocols are not optimized for these new networks. In our protocol, although each node starts with a different initial energy, it adaptively tunes its energy consumption with its residual energy and the current energy status of the nodes in the region such that the nodes remain alive for as long as possible. Our protocol is energetic sustainable, and using this protocol the network lifetime will be stable and predictable. The current clustering protocols assume the same initial energy levels for nodes; however, our protocol is optimized for HANETs where nodes are initiated with different energy levels. We validated the effectiveness and efficiency of our protocol through simulations in MATLAB. The analysis of our results showed that in comparison to the current protocols on an average our protocol reduces the network instability into 46% and improves the total network throughput by 42% and the stable phase throughput by 21% in a HANET.
