Wireless Sensor Network is a highly distributed network of small and lightweight sensing nodes which are deployed in a large number at multiple locations. These networks are helpful in monitoring the system or environment. These sensor nodes performs sensing, processing and then communicating. Now a day's these networks are applied in various fields like military, defence, forest fire, medical, crisis management etc. In this paper it has been discussed about sensor network architecture and

Since energy efficient routing protocols are of major concern in the field of wireless sensor network. Therefore in further sections of this paper it has presented a brief review of different energy efficient routing protocols proposed for wireless sensor networks. In this architecture sensor nodes are organized into clusters. Each cluster is addressed by a cluster head. Only cluster head sends messages to the base station. Fig 2.2 Clustered WSN Architecture FACTORS AFFECTING WSNs Following are some of the major factors which affect the wireless sensor networks. 913 nodes, and hence decreasing the overall energy consumption in the network. Data aggregation is affected by many factors, such as the placement of aggregation nodes, the aggregation function, and the density of sensor nodes in the network. The determination of an optimal selection of aggregation nodes is thus extremely important [16] . Delay Wireless sensor networks prove useful in many delay-sensitive applications, e.g., emergency response and plant automation. In such networks, delay measurement is of key importance for a number of reasons, e.g., real-time control and abnormal delay detection. There are mainly four factors that affect the end-to-end delay in WSNs [8]: i. Transmission delay. It is limited by the link bandwidth ii. Competition of the radio channel. Especially under a contention based MAC, a packet has to compete for the access of the channel and wait for transmission until the channel is idle. iii. Queuing delay. A large queue will seriously delay packets; iv. Path length. Generally, the more hops a packet travels, the large propagation delay it will suffer.
