Analytical Approach for Performance of Wireless Sensor Networks
Wireless Sensor Networks (WSN) have been noticed and researched in recent years. WSNs have inherent and unique characteristics compared with traditional networks. It consists of light-weight, low power and small size Sensor Nodes (SNs). They have ability to monitor, calculate and communicate wirelessly. Sensor nodes should send their collected data to a determined node called Sink. The sink processes data and performs appropriate actions. Nodes using routing protocol determine a path for sending data to sink. Sensor nodes have a limited transmission range, and their processing and storage capabilities as well as their energy resources are also limited. Routing protocols for wireless sensor networks have to ensure reliable multi-hop communication under these conditions.
