STESA: Self Transmission Energy Saving Algorithm for road surveillance

In wireless sensor & actor network (WSAN), sensors are used to sense data from environment and send this data to the actor to take appropriate action. In semi automated architecture sensed data is forwarded to the actor and then to sink. This sensor network is used for road surveillance. There are many algorithms and protocols designed to reduce energy consumption. Because of different coordination pattern and topology dependency these algorithms and protocols cannot be used directly for road surveillance application. Our proposed STESA (Self Transmission Energy Saving Algorithm) is efficient than existing one. In this algorithm, we have used only sensors for forwarding data to sink directly so as to reduce energy consumption, packet loss and delay. This is proved with simulation result.
