Cluster-to-Cluster Relay Schemes in Wireless Sensor Network
Cooperative communications is a promising technology to improve the performance of wireless sensor networks. To ensure scalability sensor networks are often partitioned into clusters, each managed by a cluster head. most of the previous research focused on the optimal communication of sensors in one cluster, very little attention has been paid to the efficiency of cooperation among the clusters .In this paper, we consider cluster-to-cluster cooperative communications where cluster head node relay data packets to nearby cluster head nodes using cooperative communications, and propose two cooperative transmission scheme and analysis on the throughput and outage probability. Finally, we demonstrate the applicability of our results through numerical examples.
