Introduction

Background
A wireless sensor network (WSN) consists of distributed sensors to monitor environmental conditions such as temperature, sound, vibration, pressure, motion or detect dimensions, to pass their data through the network to a base station for processing. Advantages of WSN over a wired system considered in elimination of wiring cost, sensors can be installed in harsh environments. Each sensor node is a combination of Radio transceiver with an internal antenna or connection to an external antenna micro-controller, electronic circuit for interfacing with the sensors, energy source, usually a battery or an embedded form of energy harvesting. Drawback of using sensors is having limited power to consume, a memory that is

However, this solution is not optimal neither it is minimal. To provide a better solution a collaboration of different parameter sensors is used to both minimize and optimize sensor usage.
Figure 2 describes a 3-axis graph of the boxes, the x-axis is dimension, the y-axis is the color and the z-axis is the weight. Figure 2a, 2b and 2c maps objects by the x-y, y-z and x-z respectively. There 11 different possible sensor positions using the 3 parameters shown in a light grey dashed line on figure 2 graphs. Using the code described in section 3, the solution set resulted in using a total of 3 sensors (d3, w1, c2) shown on a solid line in figure 2 graphs. This subset of sensors happens to be both the optimal and minimal solution.

Proposed solution:
The following section describes the code developed to find an optimal sensor solution. The first step is to consider the cost of each sensor used. The minimal sensor subset is the set with the lowest cost. The equation  describes the cost of the sensor, which simply is the summation of each of the used sensors. As described previously, most sensors used in this technique are simple and there is no significant difference in their cost. Thereby since sensors of different parameter are of the same cost, it is more effective to consider the
