PERFORMANCE IMPROVEMENT OF AUTOMATED ADDRESS ASSIGNMENT FOR PATH CLUSTER WSN USING 2-LEVEL ROUTING
Prashant Rewagad, Harshal K. Nemade · 2014
Although wireless sensor network have been extensively researched, their deployment is still a main concern. Observe that many monitoring applications for WSNs have adopted a path- connected-cluster (PCC) topology, where regions to be monitored are deployed with clusters of sensor nodes. Since these clusters might be physically separated, paths of sensor nodes are used to connect them together. Call such networks PCC-WSNs. PCC-WSNs may be widely applied in real situations, such as bridge-connected islands, street-connected buildings, and pipe-connected ponds. Show that the address assignment scheme defined by ZigBee will perform poorly in terms of address utilization. Then propose a systematical solution, which includes network formation, automatic address assignment, and 2 Level routing. Proposed system contributes in formally defining the PCC- WSN topology. Also, proposed a formation scheme to divide nodes into several paths and clusters. Then a two-level ZigBee-like hierarchical address assignment and routing schemes for PCC-WSN would be conducted. The proposed automated address assignment scheme assigns each node both level-1 and level-2 addresses as its network address. With such a hierarchical structure, routing can be easily done based on addresses of nodes.Also show how to allow nodes to utilize shortcuts. With proposed design, not only network addresses can be efficiently utilized and the spaces required for the network addresses can be significantly reduced, but also the network scale can be enlarged to cover wider areas without suffering from address shortage.
