N2 - In wireless sensor and actor networks cooperation among sensor and actor nodes introduces momentous gains compare to traditional sensing. For example, better precision in data collection by sensor nodes, and performing proper actions based on suitable decision by actor nodes. However, to get these possible gains, actor nodes need to be in proper positions. In Wireless Sensor and Actor Networks (WSAN), the number of sensor nodes is much greater than the actor nodes. Actor nodes are generally few in number but have greater abilities and can control larger area. Actor nodes are responsible for taking a localized decision which may require strong coordination and communication with neighboring actor nodes. Therefore, placement of actor nodes in WSAN is very tricky, and it requires a lot of efforts to achieve minimum delay, high throughput, larger area coverage, and better load balancing. But it may not be possible in certain applications because sensor networks are deployed on a fly. Hence, precise deployment is difficult at the time of network establishment. When an event is detected sensor nodes communicate the nearest actor node through multihop. To get better performances such as minimum delay and high throughput of the network, actor nodes must be repositioned near to the event region. In this paper we have developed a mechanism for achieving better network lifetime, low energy consumption, minimum delay, and high throughput via proper repositioning of actor nodes. Actor can find suitable coordinates for repositioning itself or some other actor based on Euclidean distance, energy of the region and number of nodes.
