Dynamic Aggregation Protocol for Wireless Sensor Networks

Abstract

Abstract-Sensor networks suffer from limited capabilities such as bandwidth, low processing power, and memory size. There is therefore a need for protocols that deliver sensor data in an energy-efficient way to the sink. One of those techniques, it gathers sensors' data in a small size packet suitable for transmission.In this paper, we propose a new Effective Data Aggregation Protocol (DAP) to reduce the energy consumption in Wireless Sensor Networks (WSNs), which prolongs the network lifetime. This work uses in-network aggregation approach to distribute the processing all over the aggregation path to avoid unbalanced power consumption on specific nodes until they run out.Simulation results prove that DAP, compared to other protocols, achieves more data aggregation percentage and less power consumption for a one data harvesting round.

Using efficiently autoregressive estimation in wireless sensor networks

“…Thus, the new parameters are sent to the sink. Recently, Said et al propose in [8] a data aggregation protocol to reduce the energy spent in wireless sensor networks. Moreover, in [9] Bayani and López find that the location of sensors plays an important role in energy consumption in single-sink scenarios.…”

Data Aggregation in Wireless Sensor Networks (WSs)- A review

“…BHCDA use the absolutely compressible aggregationfunction [1] to enhance the bandwidth utilization and energysaving as compare with EECDA.The aggregation ratio [2] increases as the number of nodes and their density in the network increase compare to other solutions that are not affected by the parameters.Further cluster adjustment and routing update [3] with a small footprint running on the nodes which indicate EHGUC-OAPR can efficiently balance the energy consumption of the whole network and proficiently improve the data delivery ratio.…”

“…But in real time applications WSNs comes up with heterogeneous sensor nodes. [2,8] 2. Many WSNs data aggregation at the base station by individual nodes causes flooding of the data which consequences in maximum energy consumption.…”

A Dynamic Virtual Force-Based Data Aggregation Algorithm for Wireless Sensor Networks

“…Li et al [7] proposed a lifetime balanced data aggregation algorithm; that is, instead of focusing on energy consumption of individual node, design a unique algorithm to balance the nodal lifetime. Said et al [19] proposed a new effective data aggregation protocol to reduce the energy consumption in WSNs; it uses in-network aggregation to distribute the processing all over the aggregate route to avoid unbalanced energy consumption on specific nodes until they run out. There still are plenty of novel algorithms such as those described in [20,21].…”
