In the design of routing protocols for opportunistic networks (OppNets), the node’s context information such as number of encounters to destination (EN), distance to destination (DI), delivery probability (PR), to name a few, is used as routing decision patterns when selecting the best next hop candidate to forward the data packets to their destination. Most routing protocols thus far proposed for...
The design of routing protocols for opportunistic networks (OppNets) generally assume that some cooperation prevail between the nodes. But, in the presence of non-collaborative attacks such as supernova and hypernova, the routing operations become a challenge. This paper proposes a defense mechanism against the misbehavior of supernova and hypernova nodes in an OppNet running Epidemic and ProPHet...
In this paper, an energy-aware version of a recently proposed History-Based Prediction for Routing (HBPR) protocol for opportunistic networks (OppNets) called energyefficient HBPR (AEHBPR) is proposed, which saves the energy consumption by avoiding unnecessary packets transmission in the network and by clearing the buffer of nodes carrying the copies of the already delivered packets. The proposed...
