In mobile ad hoc networks (MANETs), service composition faces severe challenges such as the lack of central server, node mobility and wireless network failure, which are usually not considered in web service composition on Internet. This paper designs and implements an on-demand service composition protocol for MANETs with consideration of quality of service (QoS). Based on the well-known Dynamic...
As the increasing of mobile Ad Hoc network applications, and the demand of group-oriented computer and communication, multicast routing technology has become the focus of the study. As the increasing of ...the scalability of the multicsat routing protocol becomes an important issue. In this paper, based on MAODV, an improvement protocol with policy-based clustering multicast routing is put forward...
Routing is the main research issue in the development of wireless mesh networks (WMNs). Many of the routing approaches have been borrowed from mobile ad hoc networks (MANETs) to achieve routing solutions in WMNs but are not ideal or optimal and do not utilize the characteristics of WMNs to their benefits. In this paper, we propose an improved hierarchical AODV routing protocol (IH-AODV), which exhibits...
In this paper, we propose a new routing protocol named micro sensor routing protocol (MSRP) in IPv6 wireless sensor network. MSRP is implemented in network layer and can simplify significantly routing mechanism. Also, we simplify the routing message and remove source and destination nodes' sequence numbers and reduce route request (RREQ) ID length. Route reply (RREP) is created only by the destination...
In this paper, we efficiently adapt the prominent Ad Hoc On-Demand Distance Vector (AODV) routing protocol with a reactive Local Link Repair, AODV-LR, for effective deployment in restricted power-budget and bandwidth mobile ad hoc sensor networks (MASNET). We introduce a better replacement mechanism to the local repair phase of the AODV. Our new approach is a preemptive, self-repairing AODV (called...
In this paper, a new routing protocol, called traffic-aware and low-overhead routing protocol (TALORP) is proposed. The TALORP protocol, which is an enhancements of the low-overhead routing protocol (LORP), uses backup routes to mitigate the flooding problem that is frequently used to repair link failures. It also takes into account the traffic flows on different paths toward the destination in order...
This paper aims to improve routing fault tolerance in mobile ad hoc networks by optimizing multipath routing in traditional AODV routing protocol. It tries to prove the effect of varying waiting time of Route Reply (RREP) procedure and utilizing the concepts of threshold waiting time and efficient routes on the performance of multipath extensions to AODV. A novel approach called ORMAD (On-demand Route...
In an IEEE 802.11 ad hoc wireless LAN, the listen interval (LI) of a power-saving (PS) station should be fixed at one even there is no data traffic or its remaining battery power is low. However, if the value of LI is allowed more than two (in units of beacon interval), 802.11 power management may completely fail. In this paper, we propose a novel power management protocol, named OFPM, which not only...
Ad Hoc is one sort of multi-hop, self-organization wireless network without the fixed base-station. It is the most challenging work in wireless networks and the routing layer attracts more eye than others. AODV is one of a typical kind of routing protocols among these. This paper labors the local repair mechanism of AODV. And two kinds of improved mechanism are presented. More important, an optimized...
In wireless ad hoc networks, there are great challenges of supporting real-time video transmission due to the impact of frequent link interruptions, collisions, and bandwidth limitations and so on. Based on the analysis of the multipath routing and congestion control strategy, we propose a dynamic congestion control based multipath routing protocol (DccMR). DccMR establishes and maintains redundant...
The Ad hoc On Demand Distance Vector (AODV) routing protocol is intended for use by mobile nodes in ad hoc networks. To provide quality of service, extensions can be added to the messages used during route discovery. These extensions specify the service requirements which must be met by nodes rebroadcasting a route request (RREQ) or returning a route reply (RREP) for a destination. In order to provide...
