COMMUNICATION SYNCHRONIZATION IN CLUSTER-BASED WIRELESS SENSOR NETWORK: A REVIEW

Mahadev Khatke, Pratibha Chavan

Abstract: A wireless sensor network is acquiring more popularity in different sectors. A scalable, low latency and energy efficient are desire challenges that should meet by wireless sensor network. Clustering permits sensors to systematically communicate among clusters. Cluster based sensor network satisfies these challenges as it provides flexible, energy saving and QoS. The communication efficiency and network performance degrades if the interaction between inter-cluster and intra-cluster communication are not managed properly. The proposed work uses two approaches to solve this problem. At aiming low packet delay and high throughput first approach uses cycle- based synchronous scheduling. By completely removing necessity of communication synchronization second approach send packets with no synchronization delay. The combined scheme can take benefit of both approaches.

Keywords: Wireless sensor network, clustering, communication synchronization, QoS
