Secure Optimized Link State Routing in Mobile Social Networks

摘要

Mobile social network MSN is comprised of autonomous and self-organizing mobile computing devices which do not have a fixed infrastructure but rather they use ad-hoc routing protocols for data transmission and reception. Due to the continu ous mobility of the user and working with the internet through the cellular operators on the mobility there is a need of efficient mobile social network services (MSNs) where user of similar interest in specific area under the connectivity of telecom oper ation can exchange contents like news, pictures, voice and video chatting and much more by accessing the internet. Optimized Link State (OLSR) is an IP reactive rout ing protocol which is optimized for MANET that is part of mobile social network and it can also be used for other wireless ad-hoc networks. Nodes in mobile social network network cannot perform route discovery or maintenance functions itself. This problem is resolved by using OLSR as it computes the routing distance from sending node to receiving node at preset intervals. This research paper proposed Secure Routing Protocol (SRP) OLSR Message for Mobile social network and its implementation. Performance of proposed SRP is compared to ordinary OLSR. The simulation results reveal that proposed SRP is more efficient and secure than ordinary OLSR. SRP OLSR can be used for further research towards development of a commercial demand for the MSNs routing pro tocol using Blowfish cryptosystem for encryption and decryption for secure routing in a given MSN.
