Route selection is a very sensitive activity for mobile ad-hoc network (MANET) and ranking of multiple routes from source node to destination node can result in effective route selection and can provide many other benefits for better performance and security of MANET. This paper proposes an evaluation model based on analytical hierarchy process (AHP), fuzzy sets and technique for order performance by similarity to ideal solution (TOPSIS) to provide a useful solution for ranking of routes. The proposed model utilizes AHP to acquire criteria weights, fuzzy sets to describe vagueness with linguistic values and triangular fuzzy numbers, and TOPSIS to obtain the final ranking of routes. Final ranking of routes facilitates selection of best and most reliable route and provide alternative options for making a robust Mobile Ad-hoc network.

Cognitive radio (CR) networks are becoming an increasingly important part of the wireless networking landscape due to the ever-increasing scarcity of spectrum resources throughout the world. Nowadays CR media is becoming popular wireless communication media for disaster recovery communication network. Although the operational aspects of CR are being explored vigorously, its security aspects have gained less attention to the research community. The existing research on CR network mainly focuses on the spectrum sensing and allocation, energy efficiency, high throughput, end-to-end delay and other aspect of the network technology. But, very few focuses on the security aspect and almost none focus on the secure anonymous communication in CR networks (CRNs). In this research article we would focus on secure anonymous communication in CR ad hoc networks (CRANs). We would propose a secure anonymous routing for CRANs based on pairing based cryptography which would provide source node, destination node and the location anonymity. Furthermore, the proposed research would protect different attacks those are feasible on CRANs.

A Wireless sensor network is a special type of Ad Hoc network, composed of a large number of sensor nodes spread over a wide geographical area. Each sensor node has the wireless communication capability and sufficient intelligence for making signal processing and dissemination of data from the collecting center .In this paper deals about redundancy management for improving network efficiency and query reliability in heterogeneous wireless sensor networks. The proposed scheme deals about finding a reliable path by using redundancy management algorithm and detection of unreliable nodes by discarding the path. The redundancy management algorithm finds the reliable path based on redundancy level, average distance between a source node and destination node and analyzes the redundancy level as the path and source redundancy. For finding the path from source CH to processing center we propose intrusion tolerance in the presence of unreliable nodes. Finally we applied our analyzed result to redundancy management algorithm to find the reliable path in which the network efficiency and Query success probability will be improved.
