Abstract

Based on the standard of IEEE 802.15.4b

a cross-layer protocol design combining cluster-tree formatting and mobile routing was proposed for query-driven wireless sensor networks with mobile Sink（s）.Firstly

energy consumption

network connectivity

load balancing and sub-tree depth were employed as the evaluation factors.A topology evaluation function under a multi-objective optimization model was defined to construct the stable and optimal underlying clus-ter-tree network.Secondly

the beacon frame scheduling based distributed sleep synchronization algorithm in IEEE 802.15.4 MAC was improved

which was used to maintain the network synchronization and topology correction on low duty-cycle.Thirdly

the parent-child relationships established during the topology formatting according to "first beacon"

"best links"

"top level" rules were exploited to build the two-way routing paths between mobile Sink（s） and the nodes within N-Hop range.Eventually

the topology control schemes at MAC layer and the query routing approach at network layer were completely implemented in the protocol stack of TinyOS.The experimental results show that the evaluation function can effectively reflect the quality of network formatting.Jointed with the sleep synchronization mechanism un-der the topology generated using the rule of "best links"

the N-Hop reactive routing exhibits high energy-efficiency.
