“…In line with the ideas of incorporating a knowledge plane in networking design proposed by in [21], we believe that cognitive techniques could help to deal with the complexity of management and control of fednets. One needs to investigate in which specific problem domains cognitive technology can assist.…”

This paper introduces the concept of fednets. Fednets are temporary ad-hoc federations of networks with the objective of achieving a specific common goal. Fednets are driven by purpose and opportunity. Fednets are constituted by a set of independent networks under mutually agreed rules for cooperation. The rules for cooperation are policies to control under what circumstances (context) with what networks and for what purposes cooperation is allowed. We discuss the concept of fednets by focusing on fednets formed by personal networks (PN), which are person-centric networks connecting personal devices and artefacts regardless of geographical location.

“…We take into account the contextual information from the network and MN sides, as it can be useful to avoid wrong handover decisions and, hence, bad performance of the overall handover strategy. Due to the distributed and heterogeneous nature of the information in the networks, we need a distributed knowledge base that we will refer to as the knowledge plane (KP) [13]. We introduce a novel agent-based technique to perform make-before-break handover with the help of knowledge plane.…”

An intelligent agent-based scheme for vertical handover management across heterogeneous networks

Advances in technology have enabled a proliferation of mobile devices and a broad spectrum of novel and outbreaking solutions for new applications and services. The increasing demand for all time and everywhere services requires the network operators to integrate different kinds of wireless and cellular networks. To enable this integration, it is important that users can roam freely across networks. As different technologies are involved in the current infrastructure, the problem of vertical handover needs to be addressed. To cope with the problem of seamless connectivity, several solutions have been presented. But most of them either lack intelligence or are not adaptable for reducing the packet loss and delay involved in the handover procedure. An intelligent technique is needed in order to perform the service continuity in the heterogeneous environment. This paper presents a cooperative agent based approach for the vertical handover using a knowledge plane. We propose to introduce the agents in the mobile nodes and access points to collect the necessary information from the environment. Based on this information, agents take a handover decision. A selection function is also introduced in this work which helps in choosing a best network from the available ones for handover. Finally, the proposed approach is validated with the help of simulations.

“…While many solutions exist [30,35] and have been widely deployed [9], a number of interesting research problems in simplifying network management still remain (e.g., [6,26]). Our work in this paper compliments these results by extending them to the wireless domain.…”

Self-management in chaotic wireless deployments

et al. 2006

Over the past few years, wireless networking technologies have made vast forays into our daily lives. Today, one can find 802.11 hardware and other personal wireless technology employed at homes, shopping malls, coffee shops and airports. Present-day wireless network deployments bear two important properties: they are unplanned, with most access points (APs) deployed by users in a spontaneous manner, resulting in highly variable AP densities; and they are unmanaged, since manually configuring and managing a wireless network is very complicated. We refer to such wireless deployments as being chaotic.In this paper, we present a study of the impact of interference in chaotic 802.11 deployments on end-client performance. First, using large-scale measurement data from several cities, we show that it is not uncommon to have tens of APs deployed in close proximity of each other. Moreover, most APs are not configured to minimize interference with their neighbors. We then perform trace-driven simulations to show that the performance of end-clients could suffer significantly in chaotic deployments. We argue that end-client experience could be significantly improved by making chaotic wireless networks self-managing. We design and evaluate automated power control and rate adaptation algorithms to minimize interference among neighboring APs, while ensuring robust end-client performance.
