Distributed Bandwidth Clustering Scheme for Node Cooperation in Intermittently Wireless Sensor Networks
A wireless sensor network consists of set of small set of sensor nodes which has restricted energy capacity to attain the effective data packet transmission. When the application requires high bandwidth for data transmission, then the consumption of energy might also be high, leads to the less efficiency in the lifetime of the network. To overcome the efficiency, data gathering takes place which leads to network overload. In order to address the packet collision while data aggregation in WSN, Chih-Kuang Lin, et. Al., presented a distributed and scalable scheduling technique with time slot assignment that alleviates huge data loss in sensor networks. The design of a virtual grid network minimizes the protocol intricacy and subsequently improves the scalability. But the cooperation among the nodes is less since it is based on the sensor nodes location awareness/coverage in WSN. To resolve the issue, in this work, a novel distributed bandwidth clustering scheme for wireless sensor networks is implemented, termed as NDBC. In NDBC, the cluster head is selected based on the ratio between the transmission rate and bandwidth of each sensor nodes in the wireless sensor networks. Based on the bandwidth and the transmission range of each nodes, the cooperation among the sensors are achieved based on grouping the nodes passes the data packet to the destination node. Experimental evaluation is done with the sensor nodes for better coverage in network environment against Distributed and Scalable Time Slot Allocation Protocol for Wireless Sensor Networks and its performance is evaluated with varied set of sensor nodes with measuring metrics such as bandwidth utilization, transmission rate and energy dissipation. Comparison evaluates that the proposed scheme provides 10-13% efficient in energy against the existing distributed and scalable scheduling technique.
