A Study on Data Aggregation and Reliability in Managing Wireless Sensor Networks

Abstract: Using data aggregation to reduce power consumption is a well studied area. In this paper we show a new result: data aggregation can also be used to increase reliability.In

“…The maximum number of transmits is set to an integer value that enables the non-aggregated case to meet the required reliability of delivery of all the data to the root node (of 99%). The maximum transmissions is increased by a factor consisting of the number of data elements*the policy factor for aggregated data (to reflect the increased value of the data) as shown in [10]. In each case, the data delivered by the sensing nodes is 1 Byte long, and a packet overhead of Table III), the results show the large number of packets required for every data packet to be delivered separately up the tree in the non-aggregated case.…”

“…For example, in free space, it is shown that the power a receiver receives is proportional to the wavelength of the signal (λ) and the height of antennas (H) [17]. The distance (D) between the transmitter and receiver also influences the reliability of the WSNs [15]. The environment coefficient (C E ) parameter was chosen to resolve the complex influence of environmental factors in the communications quality for the WSNs [16,17].…”
