Adaptive Multiple-Copy Multiple-Hop Forwarding in Intermittently Connected Mobile Networks

First we analyze the shortcomings of existing routing protocols in intermittently connected mobile networks (ICMN) such as high delivery delay, low success rate and cannot adaptive to the different network environment. With this in mind, we propose a new routing scheme called adaptive multiple copy multiple hop algorithm (AMM). By collecting the simple information about the status of the network, AMM dynamically adjusts the number of message copies and forwarding conditions in the process of message delivery. Furthermore, AMM takes use of the stability of the network topology during a short period of time in some local area, and establishes group connected domain to help data transmission. The simulation results show that AMM achieves a good performance on delivery delay, and reduces the network load and the energy consumption in guarantee of certain delivery rate.
