A control model of multi-purpose sensor networks by policies

Abstract

This paper describes a new framework of policy control sensor networks. Sensor networks ate shared by various applications, and have many nodes. Hence, sensor networks need to have ability to accept various applications, and to deploy application modules to nodes easily. Sensor nodes should have appropriate application modules. Afi.amework that is based on VPC on KODAM enables sensor nodes to have --qpropriate modules by assignment rules in a policy. When users only pur application policies to sensor neiworks, sensor nodes propagate the policies and perform appropriate roles in the applications. This paper also shows that sensor networks with policies change behavior corresponding to detected active W I D tags as an example.

A middleware platform to support river monitoring using wireless sensor networks

“…In a multiapplication scenario where resources are shared between competing and cooperating applications, policies provide a high level mechanism for realising cross-cutting and system wide changes. The view of sensor networks as generic platforms that will support multiple applications throughout their lifetimes has growing support in the literature [23][24][25][26].…”

“…p: is the nth prime. This is not computed dynamically, but instead is assigned based upon a well-known list of the first 10,000 primes [25]. b: is the Globally Unique Identifier (GUID) for this event type and is calculated based upon the product of the assigned p-value and the b-value of the parent node.…”

Service admission control in multi-service sensor networks

“…In the literature, a WSN where several services may coexist is referred to as multi-service network [6], multipurpose network [10], or network supporting concurrent applications [4,5]. The common idea behind all this nomenclature is to allow every sensor node performing a variety of tasks, such as measuring pressure, temperature, and motion.…”

Basically, the approaches that have been proposed focus on the levels of network ( [6,10,4]) and sensor nodes ( [4,5,11]). The network level approaches aim to delimit the group of relevant sensor nodes for the provision of every required service.…”

“…The sensor node approaches aim to suitably distribute program modules over the nodes of this group. Joining the group may be based upon adhering to specific conditions, such as user predefined admission function [4], group-keyed function [11], or agents' policies [5]. In all these approaches, the admission of any new task is out of the sensor node control.…”
