It is well known that congestion control becomes more and more important in modern grid-based routing process. In this paper, a timing-constrained congestion-driven global routing approach is proposed to obtain initial congestion-driven global routing result without destroying the timing constraint of any routing net, and a post-processing simulated-annealingbased rip-up-and-reroute improvement...

In this paper, we propose a Multicast Routing Protocol termed ZBMRP (Zone Based Multicast Routing Protocol) for Mobile Ad Hoc Networks (MANETs). ZBMRP applies on-demand procedures to dynamically establish mesh-based multicast routing zones along the path from the multicast source node to the multicast receivers. Control packet flooding is employed inside multicast zones, thus multicast overhead...

A mobile ad-hoc network is an autonomous collection of mobile nodes that communicate over bandwidth constrained wireless links. Due to nodal mobility, the network topology may change rapidly and unpredictably over time. The routing protocols meant for wired network cannot be used for mobile ad-hoc network because of mobility of network. A number of routing protocols like Destination-Sequenced D...

Load balancing is a crucial part of MANET routing protocols. Most of the currently implemented routing protocols do not account for load balancing. A number of new mechanisms and routing protocols have been proposed recently to deal with load balancing in MANET routing. A majority of the schemes proposed already add to the routing overhead which is an area of great concern since MANETS are reso...

Standard wireless sensor network models emphasize energy efficiency and distributed decision-making by considering untethered and unattended sensors. To this we add two constraints—the possibility of sensor failure and the fact that each sensor must tradeoff its own resource consumption with overall network objectives. In this paper, we develop an analytical model of energy-constrained, reliabl...

In this paper, we attempt to understand the benefits of MPLS traffic engineering through a case study. Specifically, we do a comparative study of MPLS traffic engineering in the presence of dynamic constraint-based routing compared to destination-based routing. For this case study, we use a model derived from an actual service provider network. Different control schemes that can be deployable f...
