“…The main method is used to give security from Eavesdropping of data is Encryption which uses the cryptography algorithms [6] which is divided in two parts symmetric and second is asymmetric. There are so many methods or algorithms used today for encrypting or decrypting the data through which data/information is arranged systematically, and even through which data is encrypted one by one at sender side and same process of decryption of the data is also revised by same public key and different private key at receiver side.…”

As the enormous use of internet increases day by day so as security concern is also raise day by day over the internet. In this paper we discuss the network security and its related threats and also study the types of protocols and few issues related to protocols in computer networks. We also simulate the design of 5 node wired network scenario, its packet drop rate analysis through TCP protocol using NS2 as a simulator. Analyzed the performance of 5-node network when the packet is drop down by graphical method also called as Xgraph when rate parameter is in mb and

“…• The lifetime of WSN is the total amount of time before the first sensor node runs out of the power [6]. Equations ( 2) and (3) of energy consumption are adopted to calculate the transmission cost E Tx (l, d) and the receiving cost E Rx (l) of k-bit message between two nodes where their distance is d. Then the energy expenditure for transmitting L-bit message to distance is:…”

Wireless sensor networks comprise of minor battery driven devices with restricted energy resources.Once installed,the minor sensor nodes are usually unapproachable to the operator, and thus auxiliary of the energy source is not practicable.Hence,energy proficiency is a vital design issue that needs to be boosted in order to increase the lifetime of the network. LEACH is a popular hierarchical routing protocol which efficiently maintains the energy storage of nodes in Wireless Sensor Network (WSN).The nodes using LEACH are divided into clusters.The advantage of LEACH is that each node has the equal probability to be a cluster head,which makes the energy dissipation of each node be relatively balanced. This paper studies LEACH protocol, and focuses on how to decide the next hop nodes more reasonable when the data are transmitted at the steady state. Simulation has been done in NS2 and the results show that the algorithm after improved is more energy-efficient than LEACH protocol.

“…Nonetheless, the computational, energy, and memory constraints imposed on sensor nodes and the attack environment in which they operate make them more vulnerable, as these conditions prohibit the use of more secure public-key cryptography [12,13]. Therefore, security protocols for protecting 5G connected UAV sensor networks from malicious attacks are urgently needed [14]. To achieve secure communication, key pre-distribution has become an acceptable technique, which allows sensor nodes to dynamically establish peer-to-peer relationships [15,16].…”

In recent years, UAV networking technology has become a hot topic, and it has been used in industry, agriculture, emergency, fire protection, communications and other fields. Communication technology is the key technology of UAVs, which has a decisive impact on the development of UAVs. The 5G cellular network also brings more possibilities to UAVs. With the rapid development of 5G cellular-connected drones, the security issues of their sensor networks have also attracted widespread attention. This paper studies the key management technology in the 5G network-connected UAV sensor network. Although public key encryption schemes such as RSA and elliptic curves can provide sufficient security, their applications are limited due to their extremely high demands on computing power, which conflict with the resource constraints of sensor nodes. For the security management of cluster keys, this paper introduces the concept of bivariate polynomials into key management. This not only ensures pairwise keys between any two nodes, but also performs intercluster key distribution on the generated bivariate polynomials, tests various characteristics of the generated bivariate polynomials in key management, and Simulation experiments are carried out under different orders of polynomials.
