A Novel Approach for Gateway Node Election Method for Clustering in Wireless Mobile Ad Hoc Networks

In few years, numerous efforts have been dedicated on clustering methods to use in wireless and ad hoc networks to result efficient and correct routing procedures. According to clustering, afterward of cluster formation, devices of a cluster nominated as cluster member, cluster head and cluster gateway on the basis of different roles. Among them, gateway device acts as conceptual bridge between clusters. Here one or more device may act as gateway between same or different clusters. A cluster head may be elected as suitable gateway among multiple cluster heads in situation of they all are belonging to same cluster. Cluster head election methods may employ in suitable gateway elections. This paper presents a method to elect suitable gateway. The proposed method elects suitable gateway on the basis of high rank of devices which determined use of maximum cluster belongings, device neighbors and maximum remaining battery. Proposed method is used in NS-2 simulation considering network parameters and evaluated on the basis of different simulation parameters.
