Secure Neighbour Discovery in Wireless Mesh Network

Abstract

Wireless Networks are increasingly being used for data monitoring in commercial, industrial, and military applications. Security is of great concern from many different viewpoints: ensuring that sensitive data does not fall into wrong hands; ensuring that the received data has not been doctored; and ensuring that the network is resilient to denial of service attacks [1]. Neighbourhood Discovery in Wireless network is of great importance as this will give only the legitimate nodes and all other malicious node are removed from the network. The key points which are being addressed in this report are security issues and threats and their counter measures and we have shown a privacy preservation mechanism (Penalty Based Routing Algorithm) which will ensure that the data which is being sent from source node to destination node is not been altered and monitored and also the identity of the source node is not revealed even if the intermediate nodes through which the data is transmitted is malicious. The report also addresses the method for protecting the network from packet dropping attack using Trust Value Algorithm and Ceasar Cipher encryption algorithm for encrypting the data.
