In order to fit well into the heterogeneous MANET, various protocols have been proposed, and these protocols can be divided into two types, “flat” and “hierarchical” routing, according to their routing structure. Generally, “flat” routing protocols like OLSR, which can't distinguish the difference in performance among different interfaces and make best use of the higher capacity links, do not scale...
Cellular networks operators is facing one great challenge on how to manage the exponential data traffic increase. Mobile data offloading can be a low-cost and efficient way to relieve the pressure of cellular networks. Among various offloading techniques, device- to-device (D2D) communications has gained more and more attention. However, current studies mainly concentrated on traffic offloading between...
Wireless mesh networks (WMNs) are taking advantage of multiple radio interfaces to improve network performance, and numerous routing protocols have been proposed for WMNs. However, these routing protocols can not perform well in the heterogeneous multi-radio environment with distinct bandwidth difference, for little attention has been paid to routing overhead balancing. To address this issue, we present...
We propose a position-aware routing protocol for pre-handoff on OLSR (POS-OLSR) in Vehicular Ad-hoc Networks to minimize data loss when routing handoff. We develop a function mapping node's position to link metric and calculated the best route by minimize the path metric. To fitting with position-aware and pre-handoff method, we improved OLSR protocol with a novel MPR selected algorithm and protocol...
Due to the bandwidth-limited wireless broadcast channel and node mobility in Mobile Ad hoc Networks (MANETs), reactive on-demand routing protocols have attracted extensive attention because that the routes are established only when required. Ad hoc On-Demand Distance Vector (AODV) routing protocol is a prominent on-demand one which has been used widely. However, constrained by the limited topology...
Quality-based routing protocols are proposed to restrict message flooding within only high quality nodes in delay tolerant networks (DTNs). However, different quality threshold mechanisms have diverse impact on the network and we investigate this issue in the paper. Through theoretical analysis we show that heterogeneous threshold mechanism suffers a severe nodal cost imbalance problem. Furthermore,...
Coding opportunity is crucial to the practical XOR coding scheme which can utilize these opportunities to improve the throughput of wireless networks. While the coding opportunity discovery scheme has been proposed for link-state routing protocols, there still lacks fundamental analysis on how to discover the coding opportunity effectively. In the paper we introduce the importance of coding opportunity...
With remarkable advantages over traditional networks on the aspect of flexible communication, ad hoc networks have been applied widely in real implementations. Airborne network is a brand new ad hoc application. In the case of airborne network, network node such as airplane keeps moving at fairly high speed. However, few researches attempted to probe into routing protocols performance with airborne...
