Research On3D Cell Space Routinly Algorithm In WSN

Flourishing with Internet of Things (IoT), Wireless Sensor Network (WSN), as the core component and technical support of the IoT, has been widely applied to many human fields, such as military security, environmental protection, health care, home office, industrial control, transportation, and so on. WSNs are self-organizing networks formed by a large number of sensor nodes, which could acquire, process and transmit wirelessly environmental informations, with features of large-scale, self-organizing, dynamic, reliability-oriented applications and data-based. Current researches on WSNs cover sensor technology, communication technology, network routing protocols, embedded systems, data fusion, and heterogeneous network connection, and the main research focuses on routing algorithms of WSNs.The OSI of WSNs includes physical layer, data link layer, network layer, transport layer and application layer, and WSNs routing protocols are used to define functions of layers and communication rules among layers and networks.In academia, there are already various WSNs routings, which could be divided into proactive, reactive routing, geographic routing, hierarchical routing, multi-path routing, and energy-aware routing. Aiming to find breakthrough points, the paper mainly studies the geographic routing and takes effort to make a new constructive solution combined with valuable thought from other types of routing.Considering the problem of3D void area in WSN routing,3D Cell Space Routing (3D-CSR) is presented. Analyzed the possible situations on the area which is unable to route by the Greedy Forwarding (GF) algorithm, it is the proposed algorithm that can determine the boundary of void area in3D cell space model, and accomplish the routing process with Cell Routing Mechanism. Meanwhile, Adaptive Election Mechanism is used in every single cell to keep the cell leader node active for routing and others sleep, so that the cost of network energy is balanced. Simulation results show the correctness and effectiveness of3D cell space model and3D-CSR. Compared with3D Grid Position-based Routing (3D-GPR) and3D Coordinate Face (3D-CFace),3D-CSR has higher message delivery rate and node survival rate.
