Abstract— The work deals with the healing of the coverage hole identified in a location unaware network using fuzzy logic. The hole identification is done based on the Delaunay Triangulation method and the Empty circle concept. The main contribution here is that the healing of the coverage hole is done on a location unaware network based on the energy‚ angle and distance of the nodes involved in the healing process using the fuzzy rule set. Only the partial location information like the distance

The homework problems for Module 4 are: 2-24‚ 34‚ 36‚ 38 (you only have to do part A for these problems. You do not have to do the part B graphical solutions) and 3-10‚ 12 (parts B and C for Problem 12)‚ 28‚ 30. Please use Excel solver function. I posted an annotated solution to Problem 2-5. This problem is an examplar for both the chapter 2 and 3 problems. In this example I show how I typically set up a problem. First I set up the linear programming model and then develop a parallel set-up

Homework #1 Solutions 3.1 a. Let X1 =the number of hours of process 1 used X2 =the number of hours of process 2 used The objective is to minimize the cost of producing the three products A‚ B and C. The constraints are on the demand of each product. Min 4X1 + X2 subject to 3X1 + X2 ≥ 10 (A’s demand) X1 + X2 ≥ 5 (B’s demand) X1 ≥ 3 (C’s demand) X1 ‚ X2 ≥ 0 (nonnegativity) b. From the graph we can see that the isocost line just leaves the feasible region where the demand for C and B intersect. The

C2 differentiation Maximum points‚ minimum points and points of inflection All 3 types of point are easy enough to spot on a graph: • Maximum points are the tops of ‘peaks’ • Minimum points are bottoms of ‘troughs’ • Points of inflection are where a curve stops turning ‘left’ and starts turning ‘right’ (or vice versa). An example is the point (0‚1) on the curve [pic]+1 Notes (i) Any point on a curve where the gradient is zero can be

1) The model for the transportation problem consists of 18 decision variables‚ representing the number of barrels of wastes transported from each of the 6 plants to each of the 3 waste disposal sites: = Number of Barrels transported per week from plant ‘i’ to the j-th waste disposal site‚ where i = 1‚ 2‚ 3‚ 4‚ 5‚ 6 and j = A‚ B‚ C. The objective function of the manager is to minimize the total transportation cost for all shipments. Thus the objective function is the sum of the individual
