MANETs are wireless temporary adhoc networks that are being setup with no prior infrastructure and with no centralized administrator node. MANETs have dynamic (no fixed) topology due to arbitrary (random) movement of nodes. These can be created on the fly for a single session or a temporary assignment. Routing of data packets in MANETs is a fundamental(More)
In the WiMAX (IEEE 802.16e) femtocell environment, serving Base Station (BS) should periodically broadcast neighbor BS information including femtocell to support mobility. As a neighbor list increases, it leads to increasing scanning overheads and wasting air resources. Hence, in this paper we propose a network-assisted femto BS management scheme, using a(More)
In this paper, we investigate the path length priority effect of existing just-enough-time (JET) scheme for optical burst switching (OBS) in the multiple hop network environments. And, we propose a novel hop-by-hop priority increasing (HPI) scheme using the input fiber delay lines (FDLs) at each node. Simulation results showed that the proposed FDL/delayed(More)
Mobile Ad-hoc Networks (MANETs) require a dynamic and efficient routing protocol that can respond quickly to network topology changes. Ad hoc routing protocols for MANETs are classified into: (a) proactive, (b) reactive and (c) hybrid approaches. In general, proactive routing is more suitable for a stationary network, while reactive routing is better for a(More)
Wireless mesh networks (WMNs) are attractive as a new communication paradigm. Ad hoc routing protocols for WMNs are classified into: (a) proactive, (b) reactive, and (c) hybrid approaches. In general, proactive routing is more suitable for a stationary network, while reactive routing is better for a mobile network with a high mobility. In many applications,(More)
Delay Tolerant Networks (DTNs) are one of the most interesting evolutions of MANETs where frequent disconnection of networks is there so that end to end path not establish between source to destination. When seeing routing protocols of DTNs, a forwarding and buffer management are important to be considered for successful message delivery. ‘Encounter Based(More)
In mobile ad-hoc networks (MANETs), nodes use hello messages to detect neighbor nodes and to maintain link connectivity. In a typical MANET routing, a node broadcasts hello messages at a fixed interval. However, a fixed hello interval causes a long delay of neighbor discovery (too long hello intervals) or a more bandwidth waste by unnecessary protocol(More)
