—The link quality variation of wireless channels has been a challenging issue in data communications until recent explicit exploration in utilizing this characteristic. The same broadcast transmission may be perceived significantly differently, and usually independently, by receivers at different geographic locations. Furthermore, even the same stationary(More)
—Opportunistic data forwarding (ODF) has drawn much attention in wireless networking research in recent years. The effectiveness of ODF in wireless networks is heavily depended on the choice of proper routing protocols which can provide effective source routing services. In this paper, we propose a new routing protocol named PSR for ODF in mobile ad-hoc(More)
—opportunistic data forwarding draws more and more attention in the research community of wireless network after the initial work ExOR was published. However, as far as we know, all existing opportunistic data forwarding only use the nodes which are included in the forwarder list in the entire forwarding progress. In fact, even if a node is not a listed(More)
—Opportunistic data forwarding has drawn much attention in the research community of multihop wireless networking , with most research conducted for stationary wireless networks. One of the reasons why opportunistic data forwarding has not been widely utilized in mobile ad hoc networks (MANETs) is the lack of an efficient lightweight proactive routing(More)
—Innovative routing in mobile ad hoc networks is crucial for unleashing the full potential of such networks. In this paper, we propose a new Proactive Source Routing (PSR) protocol that has a very small communication overhead but provides nodes with more network structure information than distance-vector based protocols. The value of the source routing(More)
—The existing wireless cellular networks can provide machine-to-machine (M2M) service to machine-type communication (MTC) devices deployed in large coverage areas. However , the current Long Term Evolution (LTE) cellular networks designed for human users may not be able to handle a large number of bursty random access requests from MTC devices. In this(More)
