Identifying Node Failures in Cellular Wireless Network Systems : A Probabilistic Approach
Keywords:
Node Failure Binary Scheme, Non Binary Scheme, Fault Management.Abstract
The main concept of this paper is to detect the node failures and the signal strength of the nodes. To find out these fail nodes we use two schemes, Binary Scheme and Non Binary Scheme. In Binary scheme, there are two ways one is send query and other one is receive query. In Binary scheme, the result will be in Zero’s and One’s, if the Node is active means result will be 1 and if when the node is in active means 0. In this Node A will send the status of Node B, Node B will send the status of Node C and Node C will send the status of Node D. But we cannot find the strength of each node in this binary scheme. For this reason we go for Non Binary Scheme, in this scheme we can check whether the node is in strong state or weak state to receive the signals. Same like in binary scheme Node A will send the strong or weak status of Node B, Node B will send the Strong or weak status of Node C and Node C will send the Strong or Weak status of Node D. Also while sending the files it will select the alternate path automatically for off and weak nodes. So by using the alternate nodes the files will reach the destination. And also by using the main node we can check the node status and we can check the file status also in those particular nodes.
