MPG-STAR: Mobile Process Groups Based Secured and Trusted Routing for MANets
Aakanksha Aakanksha, Punam Bedi · 2011
Wireless medium is more prone to security breaches than wired medium. The issue of security becomes critical in Mobile ad-hoc networks (MANets), due to the mobility of nodes. Node mobility causes frequent change in the radio transmission range thus changing the group membership. Members in a group communicate using the group key. Each time the group change, a new group key is to be computed in a secured manner providing backward and forward secrecy. This paper presents a secured and trusted routing algorithm MPG-STAR. The new group key is computed securely for trustworthy nodes of MPG routing protocol based on the ring based co-operation in Group Diffie-Hellman key exchange to avoid malicious or selfish nodes.
