With the technology development, the communication has become increasingly more effective, and the speed and reliability with which data travels to its destination have been greatly improved. However, new requirements have emerged. Wireless sensor networks (WSN) have the obligation to support a dynamic topology with mobile clients, for instance. In this way, structured or ad-hoc communication has been an area of intensive research and investment, which is the case of sensors. They not only satisfy the necessity of creating mobile networks quickly and effectively, but also have a wide scope of application, such as remote environmental monitoring, security systems, among others.
Although seemingly ideal, WSN have certain restraints that shape the manner with which they are employed. The major problem when dealing with networks established by them is the limited quantity of energy, which ends up limiting also the network lifetime. Thus, the way with which energy is consumed have to be carefully planned, considering not only software, but also hardware.
The objective of this project is to study routing protocols for WSN focused on the energy issue, thus developing a protocol that is as effective as able to save energy. We have considered aspects like the hot spot area, unequal sized clusters, dynamic and reactive maintenance. The implementation of this approach will take place on the network simulator NS-2, and also on the operating system TinyOS, making it possible to make experiments with real nodes. At the end, the performance will be evaluated. Further, the source codes were made available.
Achieved objectives
- Definition of an energy efficient protocol
- Its implementation on the NS2 simulator
