Towards a routing protocol based on message ferrying in split wireless sensor networks

Network splitting requires novel routing scheme different from traditional storage and forwarding manner. In the split wireless sensor networks, message ferrying method can be introduced to provide normal communication for network within tolerable delay. The definition of network delay and packet loss rate in such routing protocol was brought out. The computation method of indexes was also provided. Simulation experiment addresses to the effect of transmission rate and node cache space on average network delay and packet loss rate. Simulation results show that transmission rate of nodes and ferry can enlarge delay, while cache space can reduce packet loss rate.
