Optimizations and Performance Study of the Dynamic Source Routing Protocol
International Conference on Networking and Services (ICNS '07), 2007We have conducted a performance study of the DSR protocol, in particular, for scenarios where it presents poor performance compared to that of AODV protocol. We have also carried out two optimizations on DSR, namely: generalized salvaging mechanism and cache update of the intermediate nodes with source routes discovered during the route request packets

A cluster-based multipath dynamic source routing in MANET
WiMob'2005), IEEE International Conference on Wireless And Mobile Computing, Networking And Communications, 2005., 2006Numerous studies have shown the difficulty for a routing protocol to scale to large mobile ad hoc networks. This article proposes a cluster-based multipath dynamic source routing in MANET (CMDSR) that is designed to be adaptive according to network dynamics. It uses the hierarchy to perform route discovery and distributes traffic among diverse multiple

Multiple sources and routes of information transmission: Implications for epidemic dynamics
Mathematical Biosciences, 2011In a recent paper, we proposed and analyzed a compartmental ODE-based model describing the dynamics of an infectious disease where the presence of the pathogen also triggers the diffusion of information about the disease. In this paper, we extend this previous work by presenting results based on pairwise and simulation models that are better suited for

Dynamic Source Routing Using Directional Antenna
2015 Second International Conference on Advances in Computing and Communication Engineering, 2015A directional antenna can provide a more stable path by increasing the coverage range and reducing the no of hops. It can also solves many problems like channel interference and spatial reuse. In Mobile Adhoc Networks (MANETs), the research about directional antennas has been restricted mostly to medium access control.

Strong stochastic stability for Dynamic Source Routing
2007 Australasian Telecommunication Networks and Applications Conference, 2007Node movement in a mobile ad-hoc network (MANET) simulation is defined by the mobility model. To ensure reliable simulation results, many research papers have investigated the stability (or instability) of popular mobility models. In general, these works have been concerned with the following question: Will time-averaged measurements of ldquomobility ...

Improved dynamic source routing algorithm for MANETS
SPIE Proceedings, 2004A mobile ad hoc network (MANET) facilitates mobile hosts to communicate with one another based on wireless infrastructure. There are no base stations in ad hoc networks and the mobile hosts act as routers for data packets. Since the mobile hosts in a MANET keep moving, topological changes take place frequently in the network.

Distributed cache updating for the dynamic source routing protocol
IEEE Transactions on Mobile Computing, 2006On-demand routing protocols use route caches to make routing decisions. Due to mobility, cached routes easily become stale. To address the cache staleness issue, prior work in DSR used heuristics with ad hoc parameters to predict the lifetime of a link or a route.

Dynamic Source Routing versus Greedy Routing in a Testbed Sensor Network Deployment
2009We present our findings of an empirical performance comparison between dynamic source routing and greedy routing in a testbed wireless sensor network deployment. The environment is based on a grid ranging between 2 ×2 to 7 ×7 battery operated Tmote Sky sensor nodes.

A position information based algorithm of routing maintenance for dynamic source routing
Proceedings. 2005 International Conference on Wireless Communications, Networking and Mobile Computing, 2005., 2005It is usually to use a kind of flooding to detect and construct route during routing discovery in mobile ad hoc networks for such reactive routing protocols as dynamic source routing (DSR). When the being used routing fails, DSR must initiate a routing maintenance.

Combining opportunistic routing with dynamic source routing for wireless mesh networks
IET International Communication Conference on Wireless Mobile & Computing (CCWMC 2009), 2009Routing in wireless mesh networks presents a great challenge due to unreliable wireless links and collisions. Recently, a new routing method, opportunistic routing (OR), is proposed to deal with them by exploiting broadcast nature of wireless networks. OR relies on the global knowledge of networks to select relays and determine priorities.
