Abstract
One of the requirements for enabling two nodes to communicate through a network is the
existence of a fully connected path between them. However, there are scenarios in wireless
networks where this is not the case and yet nodes still need to communicate freely. Despite
concerted efforts to resolve this problem of unconnected wireless nodes trying to relay crucial
information, network users still experience significant communication challenges owing to
failures or non-existence of critical infrastructural links between nodes and their security
challenges. This research work is aimed at enhancing the security component of PRoPHET
routing protocol by incorporating internodes cooperation. Simulation was carried out using the
opportunistic network environment (ONE). This report presents the modeled opportunistic
network using the security aided and group encounter forPRoPHET routing protocol. Node
cooperation technique was developed and incorporated into the security aided and groups
encounter PRoPHET routing protocol in order to improve its security. For the 20-node test
scenario considered, the improved security aided and group encounter PRoPHET routing
protocol outperformed the method proposed in the security aided and group encounter PRoPHET
routing protocol of Basu et al., (2015) by 19.6%, 7.9%, 34.7% for delivery probability, hop count
and buffer timeand for the benchmark Helsinki simulation area considered, it outperformed the
method implemented in the work of Basu et al., (2015) by 25.7%, 62.9%, 55.5% with respect to
delivery probability, hop count and buffer time respectively. Results showed that, node
cooperation technique improved the security aided and groups encounter PRoPHET routing
protocol because it increased the delivery probability, reduced the latency, reduced the hop count
and increased the buffer time when tested on a 20-node test program and on the bench mark
Helsinki simulation area at the end of the simulation time of 44000 seconds.
