Abstract:

As the traditional routing protocols can not adapt to the intermittent connection of mobile networks due to the sparse distribution, frequent disruption or periodical motion of nodes, a new routing protocol marked as MSAR is proposed based on the awareness of node motion scope with the uncertainty of network status. Instead of being supported by geographical-position locating devices, the proposed protocol uses encounter histories to analyze the motion scope of nodes and chooses nodes with small overlapped motion scope to forward messages. Simulation resuits indicate that MSAR guarantees higher message delivery ratio and relative lower average delay, and that it greatly decreases the number of message copies distributed in the network and reduces the network overhead.

Key words: routing, intermittent connection, delay-tolerant network, mobile ad hoc network
