In opportunistic networks, the use of social metrics (e.g., degree, closeness and betweenness centrality) of human mobility network, has recently been shown to be an effective solution to improve the performance of opportunistic forwarding algorithms. Most of the current social-based forwarding schemes exploit some globally defined node centrality, resulting in a bias towards the most popular n...

The authors propose three variants of distributed and stateless forwarding strategies for wireless sensor networks, namely greedy minimum energy consumption forwarding protocol (GMFP), lifetime maximising GMFP (LM-GMFP) and variance minimising GMFP (VAR-GMFP), which aim at maximising the network lifetime while achieving a high forwarding success rate. GMFP selects a forwarding node that minimis...

Packet traceback in mobile ad hoc networks (MANETs) is a technique for identifying the source and intermediaries of a packet forwarding path. While many IP traceback techniques have been introduced for packet attribution in the Internet, they are not directly applicable in MANETs due to unique challenges of MANET environments. In this work, we make the first effort to quantitatively analyze the...

Mobile wireless ad hoc networks (MANETs) have become of increasing interest in view of their promise to extend connectivity beyond traditional fixed infrastructure networks. In MANETs, the task of routing is distributed among network nodes which act as both end points and routers in a wireless multi-hop network environment. To discover a route to a specific destination node, existing on-demand ...

In recent years, the bio-inspired solution has been employed to address routing optimization issue intelligently without manual intervention. In this paper, we propose a novel Ant Colony Optimization (ACO)inspired Information-Centric Networking (ICN) Routing mechanism (ACOIR) by mapping ACO into ICN. At first, we devise a content management strategy based on the storage of name prefix to help c...

Location management is important to effectively keep track of mobile terminals with reduced signal flows and database queries. Even though dynamic location management strategies are known to show good performance, we in this paper consider the static location management strategy which is easy to implement. A system with single home location register and pointer forwarding is assumed. A mobile t...

Two main problems prevent the deployment of geographic forwarding in real systems: geographic forwarding requires that all nodes know their locations, and it has trouble routing around local dead ends. This paper presents practical solutions to each problem. The location proxy technique allows a node that does not know its location to find a nearby location aware node to use as a proxy for geog...

Geocasting is an important communication service in wireless sensor networks. Most of the existing geocasting protocols assume that sensor nodes and the area of interest have accurate location information. However, this assumption is unreasonable if localization systems or schemes cannot work well. This study proposes an efficient probabilistic forwarding decision scheme for reliable geocasting...

In this paper, we propose the HEC-PF scheme, an enhancement of our previous H-EC scheme for effective data forwarding in opportunistic networks. The enhanced scheme modifies the aggressive forwarding phase of the H-EC scheme by implementing a new Probabilistic Forwarding feature, which decides whether to forward a message to a newly encountered node based on the delivery probability. Using simu...
