Tactical Edge Networks are one of the most challenging communication environments, where node mobility, constrained devices, and the wide use of wireless ad hoc channels for communications cause frequent link disruption and network partitioning. Additionally, applications running in Tactical Edge Networks often follow one-to-many and many-to-many communication models that require the nodes' cooperation...
A key property in tactical network environments is that the wireless network itself is typically the major limiting factor in how much information can be shared between users. In such environments, tactical operations often employ group communication protocols (one-to-many or many-to-many) to send information between users. This often results in situations where every message sent gets delivered to...
A peer-to-peer (P2P) network is composed of several peers. All peers may analyze data and then take some activities collaborate. Thus, assuring all healthy peers can reach agreement become very important. In real world, both peers and the transmission between peers may be malfunction, and this will cause the overall system works incorrectly. Furthermore, peers have mobility, and that will increase...
Increasing mobility and collaboration require novel schemes for group communication that actively support closed collaborations in mobile scenarios. Existing protocols do not sufficiently support, for instance, temporary losses of connections with the group. In this paper, we introduce Moversight, a new P2P group communication protocol, which is especially designed for closed groups in mobile scenarios...
Due to the advances in cellular devices and mobile technologies, now it has become possible to host Web Services (WS) on mobile devices. Web services have a broad range of service clients, whereas mobile phones have a large and expanding number of user bases. Therefore, combining these two trends by exploiting mobile devices as service providers is a promising next step. However, the usability, reliability,...
We employ the publish/subscribe model in a P2P mobile tactical networking environment to offer an effective information dispatch service. Particularly, considering the requirements in mobile tactical networks, we investigate the problem of subscriber mobility management and propose a novel proactive handoff scheme to improve system responsiveness and reliability. Results from performance analysis...
