Spectra and the exact number of Automorphisms of Paley-type graphs of order a product of n distinct primes

Autor: A, Sivaranjani, S, Radha

Paley graphs are Cayley graphs which are circulant and strongly regular. Paley-type graph of order a product of two distinct Pythagorean primes was introduced by Dr Angsuman Das. In this paper, we extend the study of Paley-type graphs to the order a

Capacity-Preserved, Energy-Enhanced Hybrid Topology Management Scheme in Wireless Sensor Networks for Hazardous Applications

Autor: A. Jawahar, S. Radha, R. Sharath Kumar

Publikováno v: International Journal of Distributed Sensor Networks, Vol 8 (2011)

A wireless sensor network is composed of large number of sensor nodes and they are densely deployed in the field to monitor the environment, collect the data and route it to a sink. The main constraint is that the nodes in such a network have a batte
