Although IEEE 802.11p technology is standardized for road safety and efficiency applications, the channel congestion problem is its key weakness necessitating distributed congestion control (DCC) algorithms on different layers of the communication stack. In this paper, we propose DCC-enabled Contention based Forwarding scheme targeting multi-hop dissemination of Decentralised Event Notification Messages...
This paper presents a multicast Delay Tolerant Network (DTN) routing protocol that uses an economic gain based routing utility for device-to-device (D2D) commercial coupon dissemination. Majority of the existing DTN routing approaches are not practically applicable to commercial content dissemination since they attempt to individually optimize performance indices such as message delay, forwarding...
In this paper, for secure routing optimization we are introducing dynamic trust management protocol in information centric network and delay tolerant network (DTN) environments. In the existing system, dynamic trust management for DTN is used to deal with the detection of the selfish, malicious misbehaving nodes and genuine loss nodes. To disrupt DTN operations, malicious nodes performing trust-related...
We present a live migration solution based on Proxy Mobile IPv6 (PMIPv6), a light-weight mobility protocol standardized by IETF. PMIPv6 handles node mobility without requiring any support from the moving nodes. In addition, PMIPv6 works with IPv4, IPv6 and dual-stack nodes. Our results from a real testbed show that network connectivity is successfully maintained with little signaling overhead and...
In this paper we present a distributed self organizing trust based clustering framework for securing ad hoc networks. The mobile nodes are vulnerable to security attacks, so ensuring the security of the network is essential. To enhance security, it is important to evaluate the trustworthiness of nodes without depending on central authorities. In our proposal the evidence of trustworthiness is captured...
Most disruption-tolerant networking protocols focus on mere contact and intercontact characteristics to make forwarding decisions. We propose to relax such a simplistic approach and include multi-hop opportunities by annexing a node's vicinity to its network vision. We investigate how the vicinity of a node evolves through time and whether such knowledge is useful when routing data. By analyzing a...
Information-centric networks (ICNs) have emerged as a prominent future Internet architecture. They work on the principle that, in today???s society, a network should be optimised towards the delivery of information, rather than the transit of messages between pre-determined end hosts. At the same time, another prominent research direction has been the delay-tolerant networking initiative, which argues...
Sink mobility has become an increasingly important requirement of various sensor network applications. Handling such mobile sink conditions brings new challenges to large-scale sensor networking. This investigation proposed a hybrid-structure routing protocol (HSRP) that combines the benefits of grid-based and cluster-based structures. Grid-based structure is designed to solve the cluster head selection...
