Summary Today's vehicle will consume high amounts of gas and produce exhaust, which is harmful to the environment. An increasing ecological awareness and the shortage of fossil fuel resources are strong motivation to develop more efficient vehicles, with no fuel consumption but without reducing driving comfort. The research work reported in the paper shows the profoundness of design and assessment of solar powered e‐rickshaw at the location with latitude of 22.75° at Indore, India. The works at macro level include pre‐feasibility assessment through analysis of 8760‐hour solar radiation and wind velocity. Duration of project is analysed by the critical path method, and vehicle cost is optimized by three different optimization techniques such as grasshopper, krill herd, and cuckoo optimization techniques. At the end, regression analysis shows the validation of cost‐optimized results. Result of profitability analysis of location of Indore shown by 5100 observation and frequency mode of solar radiation, clearness index, and temperature by 2 827 662, 1 341 397, and 13 413 557. In the modelling of solar‐powered electric vehicle system, 0.75‐KW motor is required to run a vehicle, which is powered by 500‐W solar panel, and energy is stored in 23‐Ah battery.

Security is a major concern in the field of networks. Ill egal access to resources is hazardous in the same manner as illegal access to data. It may lead to network breakdown or deadlock in the network. A major portion of research works is dedicated to improving the routing protocols or the efficiency of the network. Resource security has been of less concern. Significant work is being done in the field of security in computer networks but security and resource sharing in MANET is an issue that still demands further work. Kerberos is a trusted third party authentication protocol extensively used for security in computer networks. But this algorithm leads to significant delay in the operation hence it would be inept to apply Kerberos to provide security during resource sharing in MANET. This paper proposes a multi level security authentication (MLSA) that provides resource sharing in MANET. The algorithm is inspired by aims at improving the security of the network without affecting the performance.
