A Novel Application based Generic Cluster Creation Mechanism in Ad Hoc Networks

Abstract

-The wired mode of communication will no longer serve the purpose of our present scenario network where the expectations in communications system have been skyrocketed. Thus, wireless network with ad hoc nature will suit the present and forthcoming real world applications. This ad hoc wireless network will bind the entire globe and will reign the communication system tomorrow. But, ad hoc network has been limited by the growth factor. In order to address this issue, the clustering mechanism has been incorporated into this ad hoc network to get better results in terms of the network functionality. The ad hoc network efficiency has been improved when the clusters have been devised properly. There are various parameters which identify the efficacy level of clusters in networks. Existing cluster formation algorithms give more weight to any one of the parameters (degree, distance, energy, mobility) when selecting the cluster head of the cluster. This selection of parameters should be corresponding to the application to which the clusters are devised and cluster heads are selected. There is a desperate need for identifying the appropriate cluster head based on the importance given to parameters at various scenarios. Thus, this paper proposes NNPAC (Neural Network based Partitioning Around Cluster head), a generic method of cluster head election to fit for different applications. Implementation of this work has been carried out with the help of MATLAB simulator.

Improved Cluster Stability in the Ad Hoc Vehicle Network

“…However, this technique provides preference to a car with reduced speed than the remainder, which can cause frequent re-clustering if the other adjacent cars are moving at a comparatively greater speed. An NNPAC (Neural Network-based Cluster Head Partitioning) is suggested in [3], which attempts to select the CH based on parameters under distinct situations. The writers argue that the choice of CH solely depends on the static parameter values in most algorithms.…”
