Research Area:  Wireless Sensor Networks
Wireless sensor nodes are mainly deployed to focus the coverage and connectivity between the sensor nodes. Generally, nodes coverage range is fixed, sometimes which are placed in more distance cause out of coverage range from sender node to destination node. The network does not have any path analyzer node. This drawback is overcome by the proposed research work. After analyzing the number of packet drops during the transmission, the network identifies the out of coverage range among sensor node. It reduces packet delivery ratio and network connectivity ratio. Therefore, the proposed enhanced connectivity for nodes to measure coverage range (ECCR) is used to provide better coverage–based communication among sensor nodes. Affected routing path is detected initially since alert message packet is forwarded from the source node to the destination node. Anchor node–based path monitoring algorithm is constructed to monitor abnormal activities of each sensor nodes which are placed in the network environment. The abnormal activities indicate the more packet drop during communication since its coverage range goes out of limit. It increases the connectivity ratio and packet delivery ratio.
