In future smart environments, wireless sensor networks will play a key role in sensing, collecting, and disseminating information about environmental phenomena. These are made possible by the availability of sensors that are smaller, cheaper and intelligent. In addition, the sensors have wireless interfaces with which they communicate with one another in a network. However, these sensors have limited processing resources, memory and power. Due to such limitations, the design of a wireless sensor network depends heavily on the application and associated factors such as the environment, the objectives of the application design, cost, hardware, and system constraints. This paper investigated the difference(s) between the PUSH and PULL protocols by the use of a test-bed in different topologies of a wireless sensor network, in the “Internet of Things” concept. At the end, the better protocol was selected.
