Peer-to-peer file sharing techniques are efficient and popular ways to distribute network media contents. Aiming to improve the accessibility of media contents from mobile devices, we introduce peer-to-peer file sharing technique into delay tolerant networks (DTNs), which are formed solely by highly mobile devices and which distribute files utilizing the mobility of humans and vehicles. We first investigate...
There has been much research focusing on the routing problem in delay tolerant networks (DTNs). Much of the work has mainly focused on coding schemes for message distribution, while other work has been done on the probabilistic forwarding. Coding schemes achieve higher delivery rate via redundancy before forwarding, while probabilistic forwarding efficiently limits the abuse of the store and forward...
In this paper, we explore a quantitative approach to accountable wireless multi-hop networks. We propose using hierarchical P-Accountability to adapt the requirements of modeling a complex network environment and assess the degree of accountability in a fine-grained manner. We have defined P-Accountability and demonstrated its use in the hierarchical network environment. In addition, we apply P-Accountability...
In this paper, we focus on the query problem of trajectory tracking of moving targets in a wireless sensor network. Our motivation is to design in-network storage and querying protocols to support queries for searching a given target signature in a low query latency, high query reliability, and energy efficient manner. We propose a target trajectory query protocol, which combines index-based query...
Nowadays, faced with heterogeneous, isolated content service systems, people require peering or allied content services. Firstly, we analyze some existing content service hybrid schemes, such as CDN over P2P Architecture and Peering of CDN Architecture. Based on problem statement, we propose A Novel Web Services-based Content Delivery Service Peering Scheme (WS-CDSP), and we describe scheme architecture...
Opportunistic routing (OR) has received much attention as a new routing paradigm due to its efficient utilization of broadcasting and spacial diversity of the wireless medium. Although numerous OR algorithms and protocols have been proposed to apply to various environments and integrate with numerous techniques, as far as we know, none of the existing works have used mathematical tools such as routing...
The publish/subscribe (pub/sub for short) paradigm is used to deliver events from a source to interested clients in an asynchronous way. Recently, extending a pub/sub system in wireless networks has become a promising topic. However, most existing works focus on pub/sub systems in infrastructured wireless networks. To adapt pub/sub systems to mobile ad hoc networks, we propose DRIP, a dynamic Voronoi...
