As the scale of the network increases, especially wireless and mobile networks come into fashion. Recent advances in wireless sensor networks have led to many new protocols specifically designed for sensor networks where energy awareness is an essential consideration. In this paper, the emphasis is on the study of Hierarchical routing protocols in wireless sensor networks (WSNs) since they migh...

Mobile wireless sensor network (MWSN) is a wireless ad hoc network that consists of a very large number of tiny sensor nodes communicating with each other in which sensor nodes are either equipped with motors for active mobility or attached to mobile objects for passive mobility. A real-time routing protocol for MWSN is an exciting area of research because messages in the network are delivered ...

Wireless sensor network a powerful network contains many wireless sensors with limited power resource, data processing, and transmission abilities. Wireless sensor capabilities including computational capacity, radio power, and memory capabilities are much limited. Moreover, to design a hierarchy topology, in addition to energy optimization, find an optimum clusters number and best location of ...

In a wireless sensor network (WSN), node localization is key requirement for many applications. The concept of mobile anchor-based not new concept; however, the anchor nodes gains much attention with advancement in Internet Things (IoT) and electronic industry. this paper, we present range-free algorithm sensors three-dimensional (3D) networks based on flying anchors. nature also suitable vehic...
