Policy-Based Management for Self-Managing Wireless Sensor Networks

Abstract

In a wireless sensor network (WSN), a large number of sensor nodes are deployed over a wide area and multi-hop communications are required between the nodes. Managing numerous sensor nodes is a very complicated task, especially when the energy issue is involved. Even though a number of ad-hoc management and network structuring approaches for WSNs have been proposed, a management framework covering the entire network management infrastructure from the messaging protocol to the network structuring algorithm has not yet been proposed. In this paper we introduce a management framework for WSNs called SNOWMAN (SeNsOr netWork MANagement) framework. It employs the policybased management approach for letting the sensor nodes autonomously organize and manage themselves. Moreover, a new lightweight policy distribution protocol called TinyCOPS-PR and policy information base (PIB) are also developed. To facilitate scalable and localized management of sensor networks, the proposed SNOWMAN constructs a 3-tier hierarchy of regions, clusters, and sensor nodes. The effectiveness of the proposed framework is validated through actual implementation and simulation using ns-2. The simulation results reveal that the proposed framework allows smaller energy consumption for network management and longer network lifetime than the existing schemes such as LEACH and LEACH-C for practical size networks.

Secure policy-based management solutions in heterogeneous embedded systems networks

“…Another application of policy-based management was the SNOWMAN framework presented in [3] that allowed nodes of a WSN to autonomously organise themselves. A lightweight policy distribution protocol was developed, TinyCOPS-PR, as well as a policy information base (PIB).…”

Perspectives on next‐generation technology for environmental sensor networks

“…The organization of nodes into common networks can be self‐induced, based on the power status of each node, or induced from outside the network via instructions sent by a computer base station (Intanagonwiwat et al . 2003; Cha et al . 2007).…”

“…These central nodes can carry more of the transmission energy burden and thus reduce the need for parallel transmission paths from nodes with less access to power. The organization of nodes into common networks can be self-induced, based on the power status of each node, or induced from outside the network via instructions sent by a computer base station (Intanagonwiwat et al 2003;Cha et al 2007). The power consumed during data transmission is exponentially proportional to transmission distance (Rajaraman 2002).…”

Design and implementation of a policy-based management system for data reliability in Wireless Sensor Networks

“…Cha et al [9] proposed a policy-based network management approach for sensor nodes to organize and manage themselves. Their work is closest in spirit to our work and both are based on the policy based network management paradigm [3].…”
