In this paper, we have shown that collection of paths P i n where n is odd, cycle, triangular snake, quadrilateral snake, P 2 n are even sequential harmonious graph and also we prove that the cycle Cn be a cycle u1, u2, · · · , un is an even sequential harmonious graph. Let G be a graph with V (G) = V (Cn) ∪ {wi : 1 ≤ i ≤ n}, E(G) = E(Cn) ∪ {uiwiui−1wi : 1 ≤ i ≤ n}, then G is an even sequential...

Our work is motivated by impromptu (or “as-you-go”) deployment of wireless relay nodes along a path, a need that arises in many situations. In this paper, the path is modeled as starting at the origin (where there is the data sink, e.g., the control centre), and evolving randomly over a lattice in the positive quadrant. A person walks along the path deploying relay nodes as he goes. At each ste...

Despite the fact that commercial computer systems have been in existence for almost three decades, many systems in the process of being implemented may be classed as failures. One of the factors frequently cited as important to successful system development is involving users in the design and implementation process. This paper reports the results of a field study, conducted on data from forty-...
