چکیده
An architecture for large scale low power sensor network is proposed. Referred to as sensor networh with mobile agents (SENMA). SENMA exploit node redundancies by introducing mobile agents that communicate opportunistically with a largefreld of sensors. The addition of mobile agents shifIs computationally intensive t a s k awayfrom primitive sensors to more powerful mobile agents, which enables energy effcient operations under severely limited power constraints. An opportunistic ALOHA random access coupled with a direct sequence spread spectrum physical layer is proposed. A comparison ofSENMA with apor ad hocsensor network shows a substantial gain in energy efficiency.

متن کاملAn Energy Efficient Clustering Method using Bat Algorithm and Mobile Sink in Wireless Sensor Networks
Wireless sensor networks (WSNs) consist of sensor nodes with limited energy. Energy efficiency is an important issue in WSNs as the sensor nodes are deployed in rugged and non-care areas and consume a lot of energy to send data to the central station or sink if they want to communicate directly with the sink. Recently, the IEEE 802.15.4 protocol is employed as a low-power, low-cost, and low rat...
