The improvement algorithm of cluster-head election in Cluster-based TDMA System for VANETs

چکیده
The cluster-head plays a important role of a cluster. The cluster head is responsible for gathering and broadcasting safety messages in a cluster. If the cluster-head is elected fast, the cluster is organized rapid. In cluster-based Time Division Multiple Access (TDMA) system, the cluster-head is elected is faster than IEEE 802.11p technique. However, it is suitable for a form a small-sized cluster. In this paper, we propose a new elected-head algorithm to improve cluster-based TDMA system for forming a large-sized cluster. The analytical and simulated results show that the average number of time slots for electing a cluster-head is less than cluster-based TDMA system and IEEE 802.11p.

In VANETs, a clustering algorithm can be used to partition the network into smaller segments.Therefore, the clustering algorithms provide not only limited channel contention but also fair channel access within the cluster. In addition, they also increase spatial reuse in VANETs and efficient control for the network topology.Themain concern in the clustering algorithm is the cluster stability. T...
