When there is disconnection in mobile ad hoc network under group mobility, it falls into the delay-tolerant network (DTN). However, most existing research in DTN targets entity mobility. In this paper, we consider the routing strategy for DTN with group mobility, and propose the leader based group routing (LBGR) by making full use of group structure in group mobility. Three major mechanisms closely...
Most of the current proposed routing protocols in delay-tolerant network (DTN) are designed based on the entity mobility. In this article, we consider the routing in DTN with group mobility, which is useful in modeling those cooperative activities. The new proposed routing scheme is called group-epidemic routing (G-ER). G-ER is designed on the basis of one DTN protocol called epidemic routing (ER)...
As a challenged network, the delay-tolerant network (DTN) generally has unpredictable delay for the packet delivery due to the insufficiency of the network connectivity. Thus, it is inadequate to support some time-sensitive applications. In this paper we aim to mitigate this unpredictability of the delay in DTN to broaden its applications by proposing a new routing strategy to make use of the node...
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...
Since network disconnection will happen more frequently in mobile ad hoc network with group mobility model, the routing strategy proposed in delay-tolerant network could be applied for it. However, most of the current delay-tolerant routing protocols are designed based on the entity mobility model, not on the group mobility model. Motivated by this, in this paper we have proposed a new routing scheme...
