Abstract: Wireless network becomes unavoidable in the modern world. Routing is a major research area in every communication system which includes multi-hop wireless networks. Attacks which may be passive attacks or active attacks on routing service will collapse the entire operation of the whole network. The attacks on routing services in wireless network are simpler than traditional routing services in the wired networks. Hence, designing a secured a routing attracts many researchers. However, designing such secure routing protocol is not a straightforward procedure. In this study, a secured ant colony optimization is proposed. The ant colony optimization is a swarm intelligence based real time routing protocol which offers highly reliable and optimal routing for both single path and multi path routing. Hence, securing ant colony optimization for wireless network will lead to appreciable result.
