Security-aware adaptive dynamic source routing protocol

27th Annual IEEE Conference on Local Computer Networks, 2002. Proceedings. LCN 2002., 2003
We present SADSR (security-aware adaptive DSR), a secure routing protocol for mobile ad hoc networks. SADSR authenticates the routing protocol messages using digital signatures based on asymmetric cryptography. The basic idea behind SADSR is to have multiple routes to each destination and store a local trust value for each node in the network.

Optimized dynamic source routing protocol for MANETs

Cluster Computing, 2018
Mobile ad-hoc networks (MANETs) are wireless networks comprising of small, battery powered mobile devices/nodes. All these nodes communicate cooperatively without fixed infrastructure and able to operate alone or in coordination with wired infrastructure by using gateway nodes. In this work, the performance of optimized dynamic source routing protocol (

Strong Stochastic Stability for Dynamic Source Routing

2007 Australasian Telecommunication Networks and Applications Conference, 2007
Node 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, 2004
A 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.

Combining Source Routing and Dynamic Fault Tolerance

2006 18th International Symposium on Computer Architecture and High Performance Computing (SBAC-PAD'06), 2006
An increasing amount of current and emerging interconnect technologies rely on source routing to forward packets through the network. It is therefore important to develop methods for fault tolerance that are well suited for source routed networks.

Combining opportunistic routing with dynamic source routing for wireless mesh networks

IET International Communication Conference on Wireless Mobile & Computing (CCWMC 2009), 2009
Routing 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.

Collaborative Dynamic Source Routing using transitional trust filters

International Journal of Information and Computer Security, 2007
The DSR protocol is frequently used to establish communication in mobile ad-hoc wireless networks. For effective functioning of the protocol it is essential that no malicious nodes should participate in its execution. In this paper, we present a novel scheme for identifying and isolating malicious nodes in a DSR based network.

Securing the Ad Hoc Dynamic Source Routing Protocol

2006 International Conference on Wireless Communications, Networking and Mobile Computing, 2006
Ad hoc routing protocols are challenging to design and the need for security services further complicates the situation. So far the proposals for routing in ad hoc networks offer no security mechanisms at all, or have only partial solutions for protecting the routing.

Deploying trust gateways to reinforce dynamic source routing

INDIN '05. 2005 3rd IEEE International Conference on Industrial Informatics, 2005., 2005
A mobile ad-hoc network comprises of a number of low power wireless nodes. Each of these participating nodes endeavours to pass packets for other nodes based upon a preagreed protocol. The dynamic source routing (DSR) protocol is one of the most commonly used protocols in ad-hoc wireless networks.

Ant Colony based Dynamic source routing for VANET

2016 2nd International Conference on Applied and Theoretical Computing and Communication Technology (iCATccT), 2016
Vehicular ad hoc network (VANET) being an important application of communication and networking. Routing in VANET is difficult because it has a very dynamic behavior i.e. high mobility and different network topologies. Many topologies are developed for VANET, where they exhibit high beginning to end delay; throughput, delay jitter and also have low ...
