G-ER: Group-epidemic routing for mobile ad hoc networks with buffer sharing mechanism

In this paper we propose a new routing scheme called group-epidemic routing (G-ER), which is specifically designed for group mobility in mobile ad hoc networks. G-ER is based on one proposed delay tolerant routing protocol called epidemic routing (ER). So, it could tolerate the disconnection characteristic among groups in group mobility. By considering each group as a single node, G-ER has made a great improvement to ER, which is shown in the simulation. In addition, we introduce the buffer sharing mechanism inside each group for G-ER. Also, the simulation has demonstrated the effectiveness of the buffer sharing mechanism, especially in a more disconnected scenario for group mobility.
