A Holonic Model in Wireless Sensor Networks Yao Ye Vincent Hilaire, Abder Koukam Cai Wandong School of CS(NPU) SeT laboratory School of CS(NPU) Northwestern Polytechnical U.

The study not only analyzes the benefits of the holonic model by considering six element s , but also brings forth the concept of self-organization to construct a holonic architecture in WSNs. At last, performance analysis is presented and the result indicates that the holonic model has the characteristics of scalability, long life-time, robustness and security. 1. Introduction In our view, WSNs are a self-organize or autonomous system if an ensemble rather than a collection of sensor nodes coordinate with each other to form an entirely system that adapts to achieve a goal more efficiently. Regardless of any application domains, WSNs have the following characteristics from the viewpoint of organization under the consideration of the size constraint and constraint: (1) Single sensor node can not achieve the system’s goal. (2) Sensor nodes must act together to achieve a sub- goal, and total sensor nodes collaborate, even organize to achieve the system’s goal more efficiently and accurately, on average. (3) Single sensor node must change its internal state based on local stimuli, that is, the states of other near sensor nodes and its physical environment, Therefore, in large scale wireless sensor network, autonomous sensor nodes require to some extent the capability to group and collaborate, even organize to achieve shared objectives. 2. Holonic model A holon is a self-similar structure composed of holons as sub-structures[1]. A holon can be seen, depending on the level of observation, either as an autonomous “atom” entity, or as an organization of holons[ 2 ]. If we consider WSNs as a holon, we could say that the sink node could be considered as a super- holon from the viewpoint of the highest level. Furthermore, the super-holon is composed several sub- holons which are its neighbours. In turn, we can consider the neighbour node as a holon composed of its own neighbours of sensor nodes. A holonic model of WSNs could be depicted as Figure 1 and neighbour relationship as Figure 2 . Holon Level n Level n+! Level n+2 1 2 3 4 56 7 89 10 11 12 × × × Figure 1.

(1) At every level, the sensor nodes are divided into smaller granularity, as we call it sub-holon. As in Figure 1, at the n+1-th level, all the sensor nodes belong to only one sub-holon.
