“…routing methods can be used for transfer between nodes in network without infrastructure, which are not in direct radio range. MANET and DTN are different from each other [18]. Figure 4, MANET establishes END-TO-END path between nodes and transmits messages to the destination directly along this path.…”

A new routing algorithm for mobile ad hoc networks is proposed in this paper: an Enhanced Hybrid Social Based Routing (HSBR) algorithm for MANET-DTN as optimal solution for well-connected multihop mobile networks (MANET) and/or worse connected MANET with small density of the nodes and/or due to mobility fragmented MANET into two or more subnetworks or islands. This proposed HSBR algorithm is fully decentralized combining main features of both Dynamic Source Routing (DSR) and Social Based Opportunistic Routing (SBOR) algorithms. The proposed scheme is simulated and evaluated by replaying real life traces which exhibit this highly dynamic topology. Evaluation of new proposed HSBR algorithm was made by comparison with DSR and SBOR. All methods were simulated with different levels of velocity. The results show that HSBR has the highest success of packet delivery, but with higher delay in comparison with DSR, and much lower in comparison with SBOR. Simulation results indicate that HSBR approach can be applicable in networks, where MANET or DTN solutions are separately useless or ineffective. This method provides delivery of the message in every possible situation in areas without infrastructure and can be used as backup method for disaster situation when infrastructure is destroyed.

“…In DTNs, nodes play the role of relays who can receive messages from sources, store and forward them to other nodes, until the message arrives to the destination. When a relay can forward a message to another relay, the DTN is a known as multi-hop network because a message can be relayed by multiple nodes before arriving at the destination [1], [2], [3], [4]. While this mechanism improves the probability of success and reduces the time to deliver a message, it also increases energy consumption of the relays.…”

“…In Delay Tolerant Networks (DTN) [3,[9][10][11], the approach used by mobile nodes to communicate in the absence of a communication infrastructure is based on the so-called store-carry-forward paradigm: a source node gives a copy of its message to all mobile nodes that it meets, asking them to keep it until they can forward it to the destination. Although other routing schemes have been proposed [13,15], in this work we shall specifically consider two-hop routing DTNs [2,21], in which once a relay has the message, it can only transmit it to the destination.…”

We consider a non-cooperative game between N relays in Delay Tolerant Networks with one fixed source and one fixed destination. The source has no contact with the destination, so it has to rely on the relays when it has a message to send. We assume that the source has a sequence of messages and it proposes them to relays one by one with a fixed reward for the first transmission for each message. We analyse a symmetric mixed strategy for this game. A mixed strategy means a relay decides to accept relaying the k th message with probability q k when it meets the source. We establish the conditions under which q k = 1; q k = 0 or q k ∈ (0, 1), and prove the existence and the uniqueness of the symmetric Nash equilibrium. We also give the formula to compute this mixed strategy as well as the probability of success and the delay of a given message. When k is large, we give the limiting value of the mixed strategy q and the probability of success for the messages.
