Description:
Mobile Ad-Hoc Networks (MANETs) connect sets of wireless mobile devices on the fly’ without prior infrastructure setup and without centralized access points. Network topology in MANETs is dynamic and unpredictable, mode-to-mode communication is via wireless medium, physical protection of mobile nodes is low, and mobile devices have limited processing power and memory space. All these characteristics make MANETs vulnerable to a variety of attacks and misbehaviour. Since they are often used in potentially adverse or even hostile environments, securing MANETs is crucial before their full potential can be exploited. This research focuses on proposing a framework for security enhancements on the routing protocols for MANETs. It involves addressing security challenges in network layer and finding security solution that will consider the factors of robustness availability, fault tolerance and scalability to an optimum level. The security solution incorporates schemes that are self-organized, decentralized, power efficient and having minimum overhead to suit the unique features of MANETs. My approach uses threshold cryptography services in conjunction with power consumption management to provide the required security. Later, I plan to extend my investigation by conducting a feasibility study of the security solution when applied in Wireless Sensor Networks (WSNs) which are a special kind of MANETs. |
