WDT-CH: Watch Dog Timer Cluster Head Node based Sensor Node - Master Operations in Wireless Mobile Ad-Hoc Networks (WMAN)


Objectives: To increase the security level with improved energy efficiency for emerging application developed under Wireless Mobile Ad-Hoc Networks. Method/Statistical Analysis: In order to get the increased level of security and energy efficiency, a WDT-CH (Watch Dog Timer based Cluster Head) node is deployed to do master operation of the WMANET. This WDT-CH is increasing the network lifetime by handling network’s master operations. The network is constructed by deploying the random nodes in cluster basis. As more number of clusters is created, a stipulated number of nodes can be placed in each cluster in equal manner. WDT-CH is a watch dog timer based CH node which acts as a station keeping node. In each level, there is a main selection and redundant selection of WDT-CHCH node. At a time, one node is taken to monitor the other nodes in each cluster. By this, all nodes have health status in different clusters by the help of maintaining the status word. Also Master operations are included for obtaining node information through status word. Routing tree is used to discover the path for data communication and encryption technique in the path is used from source to sink via Key Distribution Centre (KDC). All these operations are managed by WDT-CHCH node and sensor nodes. Findings: The entire proposed approach is simulated in Network simulator software and it reveals, how effectively energy level is maintained in the network. By implementing the WDT-CH algorithm, routing tree and secured key based encryption methods the overall throughput, Packet Delivery Ratio (PDR), End-to-End delay and energy may be effectively managed. Application/Improvements: The simulation was compared with the existing approaches and found that the Packet Delivery Ratios increased to 0.18% than the existing research works.
