Daftar Isi: IMPLEMENTATION OF PREVENTIVE MEASURE FOR NODE FAILURE AND ALGORITHM FOR RECOVERING FROM NODE FAILURE WITH MINIMAL TOPOLOGY CHANGES IN WIRELESS SENSOR NETWORKS

Daftar Isi:

In wireless sensor networks,sensors collect data f rom their surroundings and forward it to the actor nodes. Actors with collaboration respond so as to achieve predefined mission. Since actors have to carry out their operation with coordination,it is required to have strongly connected network topology at every insta nce of time. Also the length of path between must be constrained so as to meet the latency requirement of the netwo rk. This paper represents the algorithm to curb down topolog y changes when a network fails and gets disjoined o r partitioned. Least-Disruptive topology Repair (LeDi R) algorithm is proposed for this task of minimal t opology changes and also changing the cluster head constant ly to prevent the failure of the sensor due to over head is proposed as a preventive measure. LeDiR uses the lo cal view of a node about the network to devise a re covery plan that relocates the least number of nodes and e nsures that no path between any pair of nodes is ex tended https://www.ijiert.org/paper-details?paper_id=140472
