Research in Wireless Sensor Networks (WSNs)

 To envision a research in the domain of  Wireless Sensor Networks (WSNs), we have to understand the basic terminology of  WSNs. WSNs is a combination of  two major technologies called wireless communication and sensors. Sensors is an actuating device, which is used to sense the environmental parameters such as fire, temperature, pollutants, vibrations, humidity, and etc. Besides, the wireless is a communication technology that permits the communication between the sensors. And the sensing and communication makes a feasible network called WSNs.


In any WSNs, we know that a sensors is an inexpensive device which has low power, small processing unit, and short range of wireless communication capability.  These inexpensive sensors are deployed in most hazardous places to sense the random events, and deliver the information to a remote base station. The deployment of these sensors can be manual as well as random (dropped through airplane or remote controlled drones).  An overview of WSNs is shown below.

An overview of WSNs
To avoid the false sensing data, and better covering of sensing field, we usually deploy more number of sensors within a sensing field. Hence, the network of these sensors is crucial to get a better information about the sensing area. To enhance the functionality of  WSNs, the various research domains are introduced such as energy saving, routing, topology control, covering, localization, fault diagnosis, and etc.

In the next post, we will begin the first step to design a WSNs using a MATLAB Tool.

Types of Algorithm and Its Complexity Analysis

Image
In this post, we will learn types of Algorithm and its time complexity analysis with examples  An algorithm is divided into two forms called iterative and recursive, as shown above. Firstly, we analyze the time complexity of the iterative algorithm and then recursive. Example 1:                           A()                           {                            int i;                            for(i=1 to n)   % loop run n times                            pf("deepa");                           } First, the above function is fall into the independent category. Hence, the running time of the loop will be n and it print the particular name n times. Therefore, the worst case time complexity of this algorithm will be O(n). Example 2:                          A()                         {                         int i;                         for(i=1, i^2<=n, i++)                         printf("deepa");                         } Similarly

Asymptotic Notations

Image
 In computer science, any problem can be solved using the programming language. And a particular problem can have multiple solutions in terms of Algorithm. To find out which one is the best algorithm for a problem, we analyse it in terms of time and space.  To define the time and space complexity of an algorithm, we use the Asymptotic notation. Mostly three types of Asymptotic notation is widely preferred to represent the complexity of the algorithm. Big-O mathematically represented as O The X-axis of the above graph showing the size of the input (n) and Y axis showing the increase in  time (t) . In the graph,   f(n) function showing the increase of time as input   size   n is increasing for a particular algorithm. Beside, the another function called cg(n) showing the worst case of f(n) . Hence, in the above graph cg(n)  is above the f(n). If we bound the time complexity or f(n) of a given algorithm in terms of input n with another function called cg(n) for all
