In this paper a Krill Herd Algorithm is applied in Smart PhoneAd Hoc Network to solve the challenges present in SPAN. The main problem faced in Smart Phone Ad Hoc Network is Synchronization, Bandwidth, Power conservation. Smart Phone Ad hoc Networks [24] (SPANs) influence the existing hardware (primarily Bluetooth and Wi-Fi) in commercially available smart phones to create peer-to-peer networks without depend on cellular carrier networks, wireless access points, or traditional network infrastructure. It differs from traditional hub and spoke networks in that they support multi-hop relays. The issues in smart phone ad hoc network is resolved using biologicallyinspired algorithm namely krill herd for solving optimization tasks. The best solution will be given by intensification process by krill herd algorithm. By using intensification process bandwidth in smart phone ad hoc network gets reduced. Power consumption is also a major issue in smart phone which affects the efficiency. By using intensification process the less power is consumed. Thus the increased bandwidth and power consumption in smart phone ad hoc network get reduced.
