Agent-based modelling was originally based on social simulation. WSNs may be deployed in large numbers in various environments, including remote and hostile regions, where ad hoc communications are a key component. The Gateway acts as a bridge between the WSN and the other network. Event is triggered whereas the report is sent to the base station in case where parameter exceeds threshold values.
However, this duty cycling may result in high network latency, routing overhead, and neighbor discovery delays due to asynchronous sleep and wake-up scheduling. Why literature matters dana gioia pdf humanity in the book thief.
One of the well known network simulator is NS2. Recently, it has been observed that by periodically turning on and off the sensing and communication capabilities of sensor nodes, we can significantly reduce the active time and thus prolong network lifetime. These intrusions need to be detected and mitigation methods should be applied.
Aggregation reduces the amount of network traffic which helps to reduce energy consumption on sensor nodes.
TinyOS is perhaps the first  operating system specifically designed for wireless sensor networks. Commercial software is opnet and used to study simulation of wireless sensor network by the help of zigbee technology.

Increased lifespan Robustness and fault tolerance Self-configuration Lifetime maximization: While encryption is traditionally used to provide end to end confidentiality in wireless sensor network, the aggregators in a secure data aggregation scenario need to decrypt the encrypted data to perform aggregation.

Wireless[ edit ] There are several wireless standards and solutions for sensor node connectivity. Online collaborative sensor data management platforms[ edit ] Online collaborative sensor data management platforms are on-line database services that allow sensor owners to register and connect their devices to feed data into an online database for storage and also allow developers to connect to the database and build their own applications based on that data.
WSN is as same as real time, database and embedded systems.

Distributed control is used in WSNs for the following reasons: Tiny, autonomous device group are worked to solve problems in wireless sensor network.
Sensor nodes are prone to failure, For better collection of data, To provide nodes with backup in case of failure of the central node.3 ACKNOWLEDGEMENTS On the submission of our Thesis report of “Energy Efficient Communication Protocols for Wireless Sensor Networks”, we would like to extend our gratitude & sincere thanks to our supervisor.
Chapter I INTRODUCTION This thesis provides an introduction to wireless sensor network , their history and potential, previous deployments and engineering issues that concern them, and the security collect and report application-specific data to the sensor node, known as a sink node.
