Data collection and transmission are the fundamental operations of Wireless Sensor Networks (WSNs). A key challenge in effective data collection and transmission is to schedule and synchronize the activities of the nodes with the global clock. This paper proposes the Bandwidth Efficient Hybrid Synchronization Data Aggregation Algorithm (BESDA) using spanning tree mechanism (SPT). It uses static sink...
Cluster-based Mobile Wireless Sensor Networks (CMWSN) has become promising research domain for researchers in the field of ICT. CMWSN has found its way directly into the real world applications only because of the availability of low-cost Sensor nodes. In the last decade, most of the researchers assumed WSN as a collection of homogeneous and stationary sensor nodes. Mobility and heterogeneity of the...
Wireless Sensor Networks (WSNs) are used for monitoring and data collection purposes. A key challenge in effective data collection is to schedule and synchronize the activities of the nodes with global clock. This paper proposes the Synchronized Data Aggregation Algorithm (SDA) using spanning tree mechanism. It provides network-wide time synchronization for sensor network. In the initial stage algorithm...
Transmission reliability and energy consumptions are two critical concerns associated with wireless sensor network (WSN) design for a long time and continuous operation. With the increase in reliability of the transmission, the energy consumption increases by affecting the efficiency of the network. This paper proposes the Schedule based Collision Avoidance (SCA) algorithm for finding the tradeoff...
In Wireless Sensor Networks (WSNs), multi-objective optimization comprises more than one objective function to be improved simultaneously where there is a compromise between two or more contradictory objectives. The optimization method must be energy competent in terms of utilization and communication. This paper proposes a novel multi-objective optimization method known as Green (Energy Efficient)-Multi-Objective...
In Wireless Sensor Networks (WSNs) a sensor node periodically produces data which is processed and then transmitted to the base station (BS) for analysis. A key challenge in the WSNs is to schedule the activity of the node in the cluster based environment for improvement in throughput, energy consumption and delay. In this regards, the paper proposes Cluster-based Myopic and Non-myopic Scheduling...
Wireless Sensor Network (WN) offers variety of novel applications for mobile targets. It generates the large amount of redundant sensing data. The data aggregation techniques are extensively used to reduce the energy consumption and increase the network lifetime, although it has the side effect of reduced reliability. In the mobile environment, it is necessary to consider the techniques which minimize...
