What is Network Lifetime

Chapter 4
Handbook of Research on Advanced Wireless Sensor Network Applications, Protocols, and Architectures
Generally defined as the time during which the network is operational. In other words the lifetime of network is defined as the operational time of the network during which it is able to perform the dedicated task(s).

Abstract
In Wireless Sensor Network (WSN), the routing protocols have been given attention because most of the routing protocols are application and architecture dependent. This chapter presents routing protocols for wireless sensor networks and also classifies routing in WSN. Chapter gives five main classifications of routing protocols in WSN which are data-centric, hierarchical, location-based, network flow and QoS aware and opportunistic routing protocols. The focus has been given on advancement of routing in WSN in form of opportunistic routing, in which the sensor nodes utilize broadcasting nature of wireless links and the data packets can be transmitted through different paths. The routing protocols for WSN are described and discussed under the appropriate classification. A table of comparison of routing protocols on the basis of power usage, data aggregation, scalability, query basis, overhead, data delivery model and QoS parameters has been presented.

QoS: Requirements, Design Features, and Challenges on Wireless Sensor Networks
It is the amount of time that a Wireless Sensor Network would be fully operative. One of the most used definitions of network lifetime is the time at which the first network node runs out of energy to send a packet, because to lose a node could mean that the network could lose some functionalities. But, is also possible to use a different definition, in which some nodes could die or run out of battery power, whenever other network nodes could be used to capture desired information or to route information messages to their destination.

Priority Encoding-Based Cluster Head Selection Approach in Wireless Sensor Networks
The network lifetime of the network is defined as the duration in which the network can perform the desired functionality. Network lifetime may be defined in different ways depending on the application such as in the clustering approaches the network lifetime is defined as the time when all the nodes in the network dies. In area coverage problem it is defined as the duration till the complete target region is monitored by at least one sensor node. In the target coverage problem the network lifetime is defined as the time duration till all the specified set of targets/points is monitored by at least one sensor node.

Sink Mobility in Wireless Sensor Networks: From Theory to Practice
This metric, commonly used in the WSN literature, is intended to reflect the time span from the network’s initial deployment to the first loss of coverage. As such, network lifetime can alternatively be defined as the ‘time until the first node dies’. The easiest to capture indicator of this metric is the maximum per-node load, where a node’s load corresponds to the number of packets sent from or routed through the given node. Clearly, the network setup that minimizes the maximum node load is the one that will ensure the maximum network lifetime.
