Efficient broadcast in wireless sensor networks can exploit backbone structures, in relation to connected dominating sets in graphs. This paper proposes the construction of a backbone for broadcast in heterogeneous wireless sensor networks having minimum energy consumption and a delay bounded by a predefined constant ℎmax. For the purpose of the paper, we assume the sensors composing the network have...
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...
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...
Nowadays, wireless sensor networks (WSN) are used in many different areas. Their capabilities have been increased in the recent years due to the recent advances in electronics. As a result, a single WSN can simultaneously manage multiple applications, generating heterogeneous traffic. Since each application has a different set of requirements, in terms of latency, reliability or energy consumption,...
