A Survey on How Dynamically Changes Topology in Wireless Sensor Network

Wireless sensor networks (WSNs) capable new applications and requires non-conventional paradigms for protocol design due to several constraints. Owing to the prerequisite for low device complexity together with low energy consumption (i.e., long network lifetime), a proper balance between communication and signal/data processing capabilities must be established. This motivates a mammoth endeavour in research performance, standardization procedure, and engineering investments on this field since the last decade. This paper aims at reporting an overview of WSNs technologies, key applications and principles, characteristics in WSNs plan, and evolutions. In scrupulous, several unusual applications, such as those based on ecological monitoring, are discussed and design strategies painted; a case study based on an actual function is also reported. Trends and realistic evolutions are traced. In this paper we have to talk about a range of objectives of existing topology and their limitation. Finally we conclude a proposed solution and its advantage and limitation in focus of our view
