Fast Data Collection in Tree-Based Wireless Sensor Networks
Fast Data Collection.pptx (Size: 203.91 KB / Downloads: 1,028) INTRODUCTION Reducing the time slots. Spanning tree. Aggregations. EXISTING SYSTEM Existing work had the objective of minimizing the completion time of converge casts. Not using of multi-channel scheduling Not considered problems of aggregated and raw converge cast PROPOSED SYSTEM Fast data collection with the goal to minimize the schedule length for aggregated converge cast. Transmission power control and multiple frequency channels on the schedule length will be reduced. ADVANTAGES we construct degree-constrained spanning trees capacitated minimal spanning trees. Improvement in scheduling performance over different deployment densities. Better for fast data collection MODULES 1. Periodic Aggregated Converge cast:- 1.Data aggregation is a commonly used technique in WSN that can eliminate redundancy and minimize the number of transmissions, thus saving energy and improving network lifetime. 2.can be performed in many ways, such as by suppressing duplicate messages. using data compression and packet merging techniques or taking advantage of the correlation in the sensor readings 2.Transmission Power Control:- We evaluate the impact of transmission power control, multiple channels, and routing trees on the scheduling performance for both aggregated and raw-data converge cast. Interference in general wireless networks, their performances for bounding the completion of data collection in WSNs have not been explored in detail in the previous studies. The fundamental novelty of our approach lies in the extensive exploration of the efficiency of transmission power control and multichannel communication on achieving fast converge cast operations in WSNs. UNIT TESTING Unit testing is usually conducted as part of a combined code and unit test phase of the software lifecycle, although it is not uncommon for coding and unit testing to be conducted as two distinct phases. CONCLUSIONS we studied fast converge cast in WSN where nodes communicate using a TDMA protocol to minimize the schedule length. We addressed the fundamental limitations due to interference and half-duplex transceivers on the nodes and explored techniques to overcome the same. We found that while transmission power control helps in reducing the schedule length, multiple channels are more effective. We also observed that node-based (RBCA) and link-based (JFTSS) channel assignment schemes are more efficient in terms of eliminating interference as compared to assigning different channels on different branches of the tree (TMCP). Once interference is completely eliminated, we proved that with half-duplex radios, the achievable schedule length is lower bounded by the maximum degree in the routing tree for aggregated converge cast, and for raw-data converge cast. Using optimal converge cast scheduling algorithms, we showed that the lower bounds are achievable once a suitable routing scheme is used. Through extensive simulations, we demonstrated up to an order of magnitude reduction in the schedule length for aggregated, and a 50 percent reduction for raw-data converge cast. In future, we will explore scenarios with variable amounts of data and implement and evaluate the combination of the schemes considered. |
