routing problem in wireless sensor network (WSN) is challenging because WSN has distributed feature, transmission requirement, data redundancy and energy restriction. The idea of ant colony optimization (ACO) has been used in design of routing algorithms for WSN. However, ant colony routing algorithms (ACRs) generally have a serious problem of slow routing discovery so far. In this paper, a feedback-enhanced ant colony routing algorithm (FACR) making use of timed-out forward ants and backward broadcasting ants is proposed to accelerate the routing process. This algorithm is simulated on NS2 and is compared to traditional ant colony routing algorithm (TACR). The results indicate that FACR achieves lower packet loss rate than T ACR under the same experimental conditions. Moreover, FACR shows a shorter end to end delay and higher residual energy rate.
This paper puts forward a routing algorithm based on Grover searching theory for MANET. It first gives the Grover searching theory and the construction way of probability branch matrix and solution path matrix which a...

Providing reliable and yet energy efficient routing protocols is of an utmost importance in Wireless Sensor Networks. Wireless Sensor Networks imply multi-hop data forwarding over unreliable and moving nodes. When selecting the appropriate routing paradigm, the main challenge is to find the right equilibrium between the quality of data delivery and the energy invested. Insufficient quality of data delivery may fail the application deployed over the wireless sensor network, while an energy wasteful protocol may significantly shorten the lifetime of the network, thus making the deployment inefficient for its purpose. In this paper we propose a new routing algorithm for WSN's, named the Data Centric Braided Multipath (DCBM) algorithm. The algorithm is designed to achieve and maintain route resiliency through multiple interleaving routing paths, capable to cope with node mobility. Simulations show that the algorithm maintains a delivery ratio similar to the previously suggested protocols, but requires significantly lower control packet overhead. The algorithm has several additional desirable properties, like loop reduction and localized path repair.
In recent years, many routing protocols and mobility management methods for hierarchical mobile ad hoc networks have been proposed, however few schemes are aimed to improve the routing performance under high node mobi...
